It doesnt show a percentage symbol when I press shift and left bracket on my fx83gtx. The shift button works, as does the left bracket without pressing shift.

[@TheCalculatorGuide]

It is SHIFT and Ans on that model

[@MartinXCV]

Thank you !

[@catalingabrielmanea2929]

Thank you very much, very helpful! I am wondering if it's possible to save time and program it to make it implied that we want to add the % on the amount. E.g. the cost of making a chocolate is 50 cents and I want to add a mark-up profit on cost of 25%. On my tablet, I just press 50+25%. With the calculator I have to press 25%x50+50 which is a bit longer I might have a higher chance of error.

[@TheCalculatorGuide]

+Catalin Gabriel Manea I would just do 1.25x50 or if you want to use the percent button 125%x50

[@catalingabrielmanea2929]

[@afreen9510]

hey.... need help..... Shift+(=( %) ....is nt working..... how to change/fix it??

[@TheCalculatorGuide]

Maybe just try a reset Shift, 9, 3, =, AC and see if that resolves it. This will clear out your memory though so make sure nothing is stored.

[@Bunnysback]

Good afternoon! Could you please clear my mind? Why when I use mixed numbers and fractions the result on cientific calculator is differe nt , for instance: 1 3/8 + 1/8 the correct result is 1/2, but on calculator the result is 5/2 , can you please tell me why?

[@TheCalculatorGuide]

Sorry what numbers did you mean 1 and 3/8 or just 3/8. I am a bit confused why you would need a mixed number if it is 3/8 + 1/8. It should just be two fractions that would give you 1/2

[@CobsTech]

Whats the software called? The on screen calculator, also Thanks, Helped me with my homework as I didn't understand how to calculate percentages at all.

[@TheCalculatorGuide]

It is the Casio fx-ES plus emulator. You can get it from ScienceStudio via Amazon at amzn.to/1UbKXwB or directly from them.

[@CobsTech]

The Calculator Guide Thanks :)

[@_FH_-pj3ef]

Thank you stampylongnose

[@ciarajoy3125]

Can you please please do a video on compound growth and decay, I'm having trouble with it.

[@TheCalculatorGuide]

I won't be doing any more videos using this model of calculator as it is older now. I already have some videos on compound growth and decay using the fx-991EX although they will be making use of the solve feature which makes these types of exponential growth and decay questions easier. You are welcome to watch them and see if they help This one from about 3 minutes in kzbin.info/www/bejne/jaWvl4CFgKqMd6c This video based on compound interest kzbin.info/www/bejne/i32UZH-poruLjrs I will be looking to do more videos shortly, some of which may be based on exponential growth and decay but it will either be using the fx-991EX or the fx-CG50 or possible the new TI.

[@ciarajoy3125]

Thank you so much!

[@orbital16]

Can I ask about this let say 100 plus another 25%. I've typed in 100+(100x25%) = 125. Is it correct? Thanks a lot.

[@TheCalculatorGuide]

Yep that works. Well done.

[@annalisasaini4727]

Life saver

[@daviddavid3621]

Tnx

[@ovelia636]

How do you work out on the calculator please: What percent of 51 is 23.

[@TheCalculatorGuide]

Input 51 and the press SHIFT and ( to get a % sign, then press x (multiply) and then input 23 ➜ 51% x 23 Press =, answer 11.73

[@tommyharris5817]

How do you calculate compound interest?

[@TheCalculatorGuide]

You need to use the standard formula, but you can input your r as a percentage if you use the percentage button

[@muhammedkamruzzaman5070]

The calculator guide i am in ur 7 and can you do a full guide PLEASE ON EVERYTHING

[@TheCalculatorGuide]

It would be a very long video lol, so I make separate videos and then playlist them.

[@tommyharris5817]

I have a Casio fx 85GTX. How do I calculate 2000-15%?

[@TheCalculatorGuide]

I would do (100-15)%x2000

[@tommyharris5817]

@@TheCalculatorGuide Thank you. It's much quicker and easier to do it on a simple calculator by typing 2000-15%.

[@TheCalculatorGuide]

You are probably right. It's easy because you have a good understanding a know what you're looking for. I find the way it's inputted into the Casio helps learner's understanding a bit better.

[@tommyharris5817]

@@TheCalculatorGuide I agree. A simple calculator ignores the law of operations which is a huge error but is useful in many other areas.

[@sahirkhan7991]

sorry buddy but this is not working, when i press shift and then bracket button, it doesn't works, i hv Casio fx-82ES ...

[@gofigureYT]

my percent does nothing, i still have to put divide by 100 tho. using fx-350ms.

[@TheCalculatorGuide]

You need to be careful if you are starting with a percentage. Just explain what you would like to do/calculate?

[@gofigureYT]

i'd followed your guide and calculation but my answer gets 2 extra zero at end, so i need to divide by 100 to get its exact answer.

[@TheCalculatorGuide]

Try the % sign at the very end of your calculation so 15 x 480% and see if that works.

[@gofigureYT]

yey it works, finally i can make proper calculation. im subbed to you now, much thx)

[@TheCalculatorGuide]

+Awang That's great. Thank you.

[@heynotizzy7493]

NO CALCULATING THE PERCANTAGE IN MATH TEST MUAHAHHAHAH

[@usachef100]

it is so much easier adding a percentage by just adding the percent amount to the number you want to increase and then hitting the percent sign button. 550 + 22% = 671

[@TheCalculatorGuide]

You are possibly right, but I wanted to link it to the idea of a multiplier which is quite often taught.

[@TanveerKhan-jp7ef]

brother: it great and work on simple calculator but not working on FX70ES

[@rattytattyratnett]

Why is this system used rather than the method on standard % method on non scientific calculators. Eg 550 + 22% = 671

[@HawxHunter]

Maths* class

[@TheCalculatorGuide]

I try to mix it up a bit with math and maths just to appeal to everyone. Math often wins as it's one less character 😉

[@aakashgupta8025]

show me how to use percent button in CASEILO fx-911W

[@TheCalculatorGuide]

Say if you wanted to calculate 15% of 200 you could input 200 x 15 SHIFT % (=)and that should give you the answer 30. I believe on this model you can add % function, but you'll have to test that for me. Input 550 x 22 SHIFT % and then + and see if that gives you 671.

[@mathef]

yes, it is working! :) Thank you!

[@SRPFC]

Just going to put this here.

[@renzomigueldelacruz4425]

come on whats the mod

[@mo_gamer4723]

How can I solve the image number in this calculator ???????????

[@TheCalculatorGuide]

"image number" I am not sure what you mean.

[@mo_gamer4723]

The Calculator Guide I mean how can I get the complx in this calculator

[@TheCalculatorGuide]

Oh sorry yes I understand. There isn't a complex mode on this calculator unfortunately. You need to get at least an fx-991EX or fx-570EX or similar or a graphic calculator.

[@mo_gamer4723]

The Calculator Guide thx 🙏

[@norwegianstud]

I paid 220€ and my buddy paid 140€, how many percent more did I pay?

[@TheCalculatorGuide]

+Glenn K Are you asking this as a general question or would you like an answer?

[@norwegianstud]

+The Calculator Guide Thx for your reply! I would like to know how to do it on the calculator. Could not find any videos describing my problem.

[@TheCalculatorGuide]

Type in (220-140) / 140%. Should give 57.14% as answer. You paid 57% more of the price of your buddies item.

[@TheCalculatorGuide]

Sorry, should be buddy's item

[@PratikRocksable]

It should be like this 480x15%= Ans:- 72

[@TheCalculatorGuide]

+Pratik Shirore Yes it works that way as well.

[@aasiasyed9713]

O my..... I don't get it... Actually in computer programing how to check %.... Is quite difficult.... That's what I want to know.... That how 5%3=2😶😶

[@sahirkhan7991]

help me ...

[@TheCalculatorGuide]

Just check if you are in calculate mode. Press mode and then 1, or watch the rest video and reset your calculator and try again.

[@laurenlomax3680]

Its good and all but your increase answer is wrong. When I put it into the calculator it was 610 not 671 like you said. Thanks for the help anyway ;)

[@TheCalculatorGuide]

+evil cupid The answer is definitely 671. Let me know where your 610 came from and perhaps I can see where it came from.

[@michealjacksonandfriends8560]

I'm depressed cause my calculator has no shift

[@Uncanny_Silence]

Alternatively: Percentage increase: 550 X 22 % + gives you 671 Percentage decrease: 360 X 12 % - gives you 228.8

[@TheCalculatorGuide]

Doesn’t work for me on this model I’m afraid.

[@reyjayme2007]

what if 3500+50%

[@reyjayme2007]

the result of my calculator is different from my Cellphone,but the correct answer is the answer of my Cellphone

[@reyjayme2007]

plssss answer me because my exam is on monday

[@TheCalculatorGuide]

You have to write it as 150% x 3500 to get an extra 50%

[@mogabriel5238]

Doesn't work

[@TheCalculatorGuide]

Totally does. Just make sure you have this model of calculator.
