Thank you. Crystal clear.

[@OA-LevelMathematics]

Glad it was helpful!

[@giuliana2364]

Thank you so much for this! You’re truly a lifesaver

[@chromatic9844]

I have a doubt. In 4(d) in compound interest formula doesn't 't' represent time in years? So why is it that we dont have to convert10 days into years?

[@btd_chiks]

You should be bigger by now

[@slayyyy_swift13]

Mam, at 42.10 whyd you divide 5095.22/400? Why'd you divide it by 400(20x20)?

[@shahir_kx]

Hello!! Would you mind doing the may/june 2024 d math paper 11 and 12?? Thank uu

[@OA-LevelMathematics]

Sure

[@TahsBsdh]

1:21:30 Why did we use this equation 12x²-4x³ instead of this 4x³-x⁴

[@OA-LevelMathematics]

Because we are working on the gradient so take the gradient of that function

[@mohammedsalman8733]

I have doubt. Can you tell me in question 7 c ( ii) what formula did use 1:04:14

[@OA-LevelMathematics]

Law of cosine

[@teddy1308]

Thank you so much, I think I have hope after watching in you

[@BakedPotatoret]

thank you

[@silent_boi1805]

i dont understand question 5 b(ii) why did you multiply 95 and 6? after that how did you get 114? why 114? and why 5-114? why does that have to do with -109? what does 5-114= -109 indicates?

[@OA-LevelMathematics]

This is the method of factorization.
If you are not clear then first revise the topic of factorization with simple examples and then the complex ones

[@takshjain2444]

for 10a can we write dcb instead of bcd

[@OA-LevelMathematics]

Yes

[@riyanroy2870]

This HELPED ME ALOT , THANKSS

[@OA-LevelMathematics]

You're welcome 😊

[@smartfeaturesandtech]

I've exam in October November any tips please

[@OA-LevelMathematics]

Practice

[@mohammedsalman8733]

I have a doubt in question 3 (b) isnt the formula supposed to be p×r×t÷100?. Because i am confused

[@OA-LevelMathematics]

Simple Interest Formula
Simple interest is calculated with the following formula: S.I. = (P × R × T)/100, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years. The rate of interest is in percentage R% (and is to be written as R/100, thus 100 in the formula).
Amount = Principal + Simple Interest
A = P + S.I.
A = P + PRT
A = P(1 + RT)
