Answer 3

Ye, I am familiar with it. It has been a long time since I have solved an equation like this. The answer I got is 19. I wanted to check my work.

Answer 4

well first work out the parentheses from the inside out
so we have 8-6 = 2
then 5 * 2 = 10
10 / 2 = 5
5 + 45 = 50
50 / 5 = 10

Answer 5

the -3^2 is ambiguous
it might mean 9 or -9

i think its -9
because if the -3 is to be squared it should be (-3)^2

Answer 6

so this gives -9+ 10 = 1

Answer 7

-3^2 is a subtraction and an exponent - the exponent is processed first
