We weren't taught to use desmos,only algebra,so this serie really hepled me out as I was wondering wich questions I would use it for. Appreciate your effort thank you very much!

[@Tutorllini]

You're welcome! Best of luck on your test Dunia!

[@natalinatali7375]

Cant express how much I love this man... explains everything clearly and is MASTER on what he's doing. None of the teachers helped me as much as u did, no one teaches you how to use Desmos and all those stuff so I was in complete vagueness. I'm very grateful for you

[@Tutorllini]

Thanks for your kind words! Good luck on your exam - let me know how you do!

Hi sir, 10:19 what can we write in for a student produced response because we found that P=-40% or 40% decrease. since we cannot add letters to student produced responses, will it be -40 or just 40. I need help please someone explain.

[@Tutorllini]

They will phrase it as a decrease in the QUESTION so you would just put 40 as the answer. Problem Sette series has lots of problems like this. I hope this helps!

[@alik6422]

hi great vids. i had one question that how would we know that at 9:30 the sales tax is on the price after discount since in real life the tax is on the price without discount but in this case it's different. if we do tax on the real price our ans would come different as well. could you pls explain this.

[@Tutorllini]

It doesn't matter if you do the tax or the discount first. Multiplication is commutative. 55x0.7x1.08 is the same as 55x1.08x0.7. Does this help?

[@alik6422]

​@@Tutorlliniyes but my question for this case was whether we'll do it this way (55*1.08)-(55*0.3) which gives 42.9 i.e different from what we got in the vid

[@Tutorllini]

@@alik6422 Yeah that would be wrong. The SAT is almost exclusively designed for you to use Percent Multipliers. You are trying to do it like you learned in 7th grade (which I don't recommend). Mastering percent multipliers will help you get a lot of questions correct! When is your exam? You should check out my Percents video which goes into far more detail and includes a free worksheet: kzbin.info/www/bejne/e2rWcoKGm6x-qa8

[@alik6422]

@@Tutorllini ah alright then. Thank you sm. I have my exam on the 3rd of Dec. I'll surely look into the worksheet as well. Thnx.

Hey man I'm taking the exam this November and I had a doubt. Is the desmos calculator allowed in all sections of the DSAT math tests ? Is there any specific section with no calculator like PSAT ?

[@Tutorllini]

Hi! Desmos is allowed on all math questions on both the Digital SAT and Digital PSAT.

[@banzaitt1694]

whats the shortcut key for multiplication or 'times' in the keyboard?

[@Tutorllini]

SHIFT 8

[@zavuh]

is there a video focusing on quadratics w constants?

[@zavuh]

i cant post the image but similar to question 22 on SAT Practice 4 from bluebook module 2

[@Tutorllini]

@@zavuh Yup! I have an entire video with free worksheet (Ottocento #16) going over these: kzbin.info/www/bejne/j4e3dWqAm9yqhLs You should probably watch Ottocento #13 Basic Quadratics first. Does this clear things up for you?

[@zavuh]

​@@Tutorllini subbed + ty! didnt realize it was in a different playlist

[@Tutorllini]

@@zavuh You're welcome mate! Take a look at the Problem Sette playlist after you are done: kzbin.info/aero/PLf3ypEs9Kobgeg-L9V8Z8ZT7gdAYZfJlt There are similar "Advanced Parabolas" questions in PS#2, PS#6, PS#7, and PS#10 among others. Also be sure to check out my Quadratics Formula Sheet: kzbin.infoUgkxoBKR2bRTPVWfgovg4ZFE_Gh62PCiBEMv Best of luck on your test - spread the word!

[@zavuh]

@@Tutorllini some of those are really tough. should i expect those on the december sat? all practice tests are really easy and i get a 780+ usually so now im worried

[@yashrajrobo3083]

Hey I entered this in graph x+80% of x=y y=2000 I get x value as 1111.111 when I put x values on desmos it gave me y=1999.9998 Can you help me? 1999.9998

lovely

[@Jamric-gr8gr]

I realky appreciate your digital SAT serise. Could you please make a video on how to solve word problems involving the slope intercept form "y=mx+b" using the Cassio FFX? EX: A window repair specialist charges $220 for the first two hours of repair plus an hourly fee. for each additional hour. The total cost for 5 hours of repair is $400. Which function f gives the total cost, in dollars, for æ hours of repair, where > 2?

[@Tutorllini]

Desmos is definitely better for this! See Desmos Lesson on regression and see my work below: www.desmos.com/calculator/ly80a0mhsz
