Answer 5

do you know order of operations (PEMDAS)?

Answer 6

when you have an expression like that it is often unclear what you need to do so you carry out PEMDAS... order of operations:
P: parenthesis
E: exponents
MD: multiplication division
AS: add subtract

Answer 7

do P first... whatever is in the parenthesis..(3-5)=-2

Answer 8

4-6*(3-5)
4-6*(-2)

then you do multiplication next
4-(-12)

then you do subtraction
4-(-12) = 16
