To everyone wondering how to store after clearing RAM, you will thank me for telling you this! 1. Go (2nd) (+) to memory 2. Then go (8) or group 3. Create new 4. Name it anything you want 5. Afterwords you'll be prompted to choose what you want to save, go to Prog... 6. You must select two programs, otherwise it won't go through and you will receive a prompt. Typically I choose CLEAR, UNCLEAR, and (Program of choice). Make sure you have all programs you wish to save, otherwise you will lose other unmarked programs. 7. Now it will say something telling you it was done. 8.WARNING: MAKE SURE YOU FOLLOWED THESE STEPS TO THE TEETH OTHERWISE YOU WILL LOSE ALL PROGRAMS 9. To test, follow step 1. and goto reset, and then (1) then (2). you will receive RAM cleared message. 10. To retrieve the files, follow steps 1-2 11. Goto UNGROUP and then your files will be reloaded. 12. YAY! now you can get away with (enter your objective here) Why should you do this? You can sneak around professors and teachers who actually check the program list, this hides it from them unlike ARCHIVE. You can save programs without fear of losing.

[@mapletongal]

Thanks a lot. It worked for me after I checked the program a couple of times and found my syntax errors.

[@masrerchief117]

***** Hey there, while I was testing your program in my calculator, I noticed that B (the one that is not in the square root) would always come out negative, even if the Input B was a negative, so I looked at the code to see what was causing the problem and found out that by stating Input B has to be greater than 0, it would not be multiplied by -1, causing that all negative inputs would remain as negative, so I changed that if Input B could not be equal to 0, then it would multiply Input B negative values by -1 and store in B Code: :If B>0 :Then :B(-1) Fix: :If B≠0 :Then :B(-1)

[@HAMHOTPOT]

this is great stuff,, thanks very much! keep making videos!

[@adaezeanaebonam9290]

Lol the same thing happened to me too! But your videos are amazing!! Thanks so much!!

[@fernandoklipll]

thank you so much. very nice video!

[@keithaduhaney5515]

THANK YOU !!!!

[@milkcaketaeshop]

I have the TI-84 Plus CE calculator. I followed the code correctly however, when the solution appears, the answer is distorted. It cuts off parts of the X values. Can you please help?

[@alusavin7244]

Is there some way that we change this code so that instead of "NO SOLUTIONS" it displays the answers in terms of i? (the imaginary number)

[@MasAkaVenom]

LOL yes your program is nicer than the others on youtube

[@lukeswift386]

I noticed that after it does its calculations it stops at the 2nd to last part at the negative b- +or- the square root of b2-4ac/2a.

[@Amita23]

I know you haven't been active as of late, but could you possibly make a program for quadratic formulas that is compatible with imaginary solutions? I'll be working on one and if it works, I'll reply to this post with the program. Thanks! :)

[@allprofitgang2838]

can you make a video on teaching us the TI calc programming language?

[@ah072965]

For the new color graphing calcs, you have to change the numbers after the word "text" and "line", play around with the first number, as that corresponds to vertical position

[@aidanknoll1019]

Thanks

[@aidanknoll1019]

Can you tell me what you changed your numbers to?

[@allie329]

My screen at the end looks crazy! (The first 2 answers cut each other in half, and the division line is at the bottom) Can you please help? Thank you :)

[@jtfromthecity4064]

Can you please show the TI-84 Plus CE version please? I typed everything for my answers to be unreadable I think its the measurements because the numbers are cut off and the division line is way under.

[@sista7714]

will this program also work for completing the square....I am partial towards your programs if not can you recommend one.

[@milkcaketaeshop]

Which are the values that I have to change in the "text" lines on the Ti-84 Plus CE???!!!!

[@wilsonmorris1567]

Is there a way to put into the program and make it solve the equations that include i

[@Green83184]

This helps but for some reason when I try to graph something my last answer from the program shows up in the backround of my graph

[@lisajones3706]

Dom can you show this program on the TI 84 Plus C Silver

[@lorenzocole8166]

I just recently purchased a TI-84 PLUS CE with Python. Would this code be able to work on that calculator ?

[@jack8998]

Hey! Just finished up the program except I'm encountering one small problem. My second X solution (for the problem at the end) came out to -5.772002, but everything else was okay. I doubled checked the code to see if anything was off and found nothing. I might've missed something, but do any ideas of why this is happening?

[@josephabboud1548]

I have this equation 4x^2+5x+9 I get no solution is there any way to display the answer with the imaginary number which would be -5+/-i√119/8

[@sarahpark5772]

Hey the fraction line doesn't show up, but everything else does... Do you know which line of the code I went wrong? Haha, if not that's fine too. Thanks so much for the video - really helpful :)

[@adamepstein9429]

How did you learn so much about programing calculators? :))

[@gardzilla13]

Hey not sure if your channel is still active but would you mind sharing how to delete an extra space between lines of code? I messed up and hit enter too many times, showing an empty line between : and : I'm SUPER new at this so appreciate the help. Thx for sharing this program!

[@madbarr]

just go to the edit PGRM screen (PGRM button then right arrow over) go to the blank line and hit the DEL button on the top. third button next to MODE. that's what worked for me.

[@lukeswift386]

When I run the program it does what happens on yours but it didn't give the final points.

[@jeffwinkle7738]

***** I made the program and all and i read some of the comments and i checked to see if my calculator graphed still. The graphed line shows up but not the X and y axis. Please help?

[@TheScantick]

tried using these codes on my Ti-84 Plus C Silver Edition and it works but I can't see anything almost as if the screen freezes. Is this normal. Do I need other coding since it is the color screen?

[@michaelbass9592]

To fix the alignment issues and size of the answers on the output screen the following lines needed to be changed for TI-84+ silver edition... All of the text lines need to be changed... :Text (-1,1,1, "X= ",D) :Text (-1,24,1, "X= ",E) :Text (-1,48,1,B,"+/-sqrt(",B^2-(4*A*C),")") :Line (-10,1.5,-2,1.5) :Text (-1,75,18,2A)

[@kylebabcock5756]

+Michael Bass sorta worked.. it looks a little strange on my screen! -__-

[@kylebabcock5756]

+Michael Bass Question: why do you have the strikethrough font on the third text line?

[@DarkShadowsGuardian]

I don't get what's wrong, it shows the results then flashes to error screen where it says the -10 is the problem. Help?

[@babybear981]

i followed your video and even went over it 4 times and i get a different first number i get 4.5 instead of 1 please help

[@clairealbertson3754]

I programmed my calculator but everytime I use it, it glitches how do i fix that?

[@ThePicaGreen]

is there a way to do this on a TI-83? or am i out of luck?

[@valeriewilliams5140]

I programed the formula correctly, but for some reason it comes out really small, cutting off the 1st and 2nd solution. Can anyone tell me how to fix this, please? I tried the zoom but that does not work. Thanks in advance for your assistance

[@motleycrue101]

Is there any difference for TI-84 Plus C silver edition? Because my display isn't working correctly.

[@JFroTheMusician]

+Kyle Smith +Hannah Whitsell If it doesn't display the way he has it above, that means the firmware on your calculators is out of date and you would need to update it if you would like to see it like that.

[@pookeywookie]

I have tried this a million time and I keep getting syntax error. I copied the program from the description and its just not working on my TI-84 Plus Silver

[@21ukraine]

can you give us a folder of all ur programs

[@jeffwinkle7738]

None of my graph lines will show up? Andy help?

[@12355Boss]

It worked thanks, but i can't get the line to draw

[@mymod123]

Can you upload the file from the calc to drive and share it?

[@JacksonWelch]

Too bad. I'm in geometry this year. I needed this last year when I was in algebra 1.

[@noellelyons3236]

I have the ti 84 plus c silver edition and the answer does come out distorted. It is as if the 2 answers are cut off. any thoughts on how to adjust the program so the final answer displays properly?

[@NoudH]

+Noelle Lyons try this : Text(1,1,"X= ",D) :Text(8,1,"X= ",E) :Text(15,1,B,"+/- √(",B^2-4*A*C,")") :Text(24,18,2A) change the first numbers to something bigger (for instance instead of 8 to 15 and instead of 15 to 21 etc.) :Line(-10,2.9,-2.3,2.9) change the 2.9 and 2.9 to something lower(depends on value used above), until it lines up (no pun intended :P)

[@TitaniumWolf12]

@@NoudH If you're using a TI 84 Plus CE use: :Text(0,1,"X= ",D :Text(15,1,"X= ",E :Text(30,1,B,"+/-√(",B^2-(4*A*C),")") :Line(-10,4.8,-2.3,4.8) :Text(50,18,2A)

[@adamy.109]

When I calculate everything, it's fine, but when the display part of it turns up, it's all a glitch. I wonder if the difference between the TI-84 silver edition and the TI-84 silver edition C is the reason?

[@Preslee76]

I’m having the same issue

[@lisajones3706]

Mine goes to error

[@MrKlyde44]

My fraction line is all messed up and my 'x=' is all messed up

[@reharlan]

Same here

[@MrKlyde44]

I edited some of your text coordinates

[@steffanhilpert1036]

for the colored calculators such as ti-84 c/ce, the display is disorientated. How can i fix it?

[@wesleybedford3259]

+Steffan HIlpert Im trying to figure that out too. Have you gotten it taken care of?

[@jaydenstone1318]

[@ethanhe8728]

same

[@Preslee76]

Same

[@dylansmith591]

I got it to work but I had to tweak the code alot

[@mordecaihunter9411]

whenever I input the B value the answer displays negative B even if the entered value is a negative. It should read positive. what am I doing wrong?

[@elbeantako8411]

Diego Rodriguez has the fix for this ☝️

[@yager4092]

You need a cover for your calk.

[@jeffboyack5387]

I have the TI-84 plus c silver edition and the answers for x are on top of each other and the line is in the wrong spot does anyone know how to fix it I have repetitively checked to see if I have the same program and it is correct from what I have seen and it still isn't working.

[@Parkman696]

I know this is late, but the formating for "text (" is different on newer calculaters. Simply put, 1,1 would stay the same, 7,1 would become 15,1 and 15,1 would become 29,1.

[@marymontana265]

Hey! for some reason it keeps popping up no solution. I went through the text of the program and also the video. Does that sound like a normal fixable problem? The problem you worked out displays the same answer but the X=1 and X=-4 are cut in half and the division symbol is under the 2A part... any solutions? It's the TI-84 plus c silver edition.

[@ah072965]

For the new color graphing calcs, you have to change the numbers after the word "text" and "line", play around with the first number, as that corresponds to vertical position

[@Preslee76]

I have the TI 84 plus CE and these are the changes I made which finally worked. Starting with the first TEXT line: Text(1,1,”X= “,D Text(20,1,”X= “,E IF B = (does not equal) 0 (sorry don’t have the correct symbol on my phone) this fixes if you have a negative for B THEN B*-1 sto B GOTO 45 ELSE LBL 45 Text(40,1,B,”+/-^(“B^-(4*A*C),”)”) I do not have the square root symbol so the first ^ is equal to square root, the 2nd is equal to B squared LINE(-45,6.0,-2.3,6.0) TEXT(60,28,2A) I hope that fixes the alignment issue and the negative b issue.

[@shalaew]

I have loaded 4 different codes from 4 different people and I am getting frusturated!! NONE OF THEM ARE WORKING! I have a ti84 plus C silver Edition calculator. I made sure all the codes were right. I can add the a,b,and c values but when I put enter to get the answer I get ERROR: DOMAIN

[@smithroy482]

Shalae Wheeler Hi, I was wondering if you where ever able to get it to work?! I haven't and been looking.

[@potatoboigames]

I'm having troubles too. The code works but the answers to the code shows up pushed together. I can't see what the x's are but just the last part. I was wondering if there was some way to fix this. Thank you!

[@Parkman696]

I know this is late, but that is because the graph formating is different on newer calculaters. For every "text(" command, you must add 7 for every line below 1. For example, instead of being 8,1, it would turn into 15,1. 15,1 would become 29,1. Hope this helped!

[@Preslee76]

would this work on a ti 84 plus C? because the program somewhat works but when it shows the final answers text its all distorted

[@johnflavio4985]

yeah thats what happened to mine as well

[@glenmusick687]

It's a difference in the screen resolutions. I changed the second text for the value "E" to Text(20,1,"X= ",E) Also changed the equation line to: Text(40,1,B,"+/-√(",b^2-(4*A*C),")") and Text(60,28,2A) Hope this helps.

It will start to work then I get the syntax error. It shows the first 2 lines and then stops. Please help me figure out what I'm doing wrong!! I have an 84 Plus C

[@dsummerssummers15]

Glen Musick did you just get rid of the "+/squareroot("b^2" and just kept the (4*A*C),")") or what? I tried it with and without it but it still doesn't work

You have a discrepancy in your code vs what you inputed on the calculator: On the instructions able you wrote: :Text(15,1,B,"+/- √(",B^2-4*A*C,")") In the video you input: :Text(15,1,B,"+/- √(",B^2-4*A*C),")")
