Is correct
[ 5 3 ]
[ 8 7 ]
5*7 - 8*3 = 35-24 = 11
[ 5 3 ]
[ 8 7 ]
5*7 - 8*3 = 35-24 = 11
Correct!

How can you get the number 1000 by adding eight numbers 8s?
Find X+Y . If
4 -> 17 -> 8
5 -> 26 -> 8
8 -> Y -> X
Quoted from "malandrino"
Find X+Y . If
4 100 0
5 145 20
6 200 0
7 265 60
8 x y
X= 265+75 =340
Y= 3*4*0 =0
X+Y=340+0=340
Solution= 340

What is the derivative of 3*sin^2(x)?
3sin2x
Correct! I honestly forgot about that identity
6*sin(x)*cos(x) would have also been acceptable
