Question

Multiply
How do I multiply these number

(1). (-3)^3-(-8)(-2)

(2). -9^2-(-6)^2

Answer 1

Use the order of Operations to decide what to do first.
1. Do what is inside Parenthesis or brackets
2. Do exponents
3. Do multiplication and division
4. Do addition and subtractions

Problem 1:
Do the exponents first
(-3)^3= (-3)X(-3)X(-3)=?

Then do the multiplication (-8)X(-2)=?

Then subtract your answers



Problem 2
Do the exponents first
then subtract

Answer 2

Use order of operations (Bedmas)

(1). (-3)^3-(-8)(-2)
first, do the exponents which is (-3)^3 which equals -27
then multiply (-8)(-2) which is 16
the new equation now is:
(-27)-16=-43

(2). -9^2-(-6)^2
first do you exponents, -9^2=-81
then (-6)^2 is 36.
the new equation now is:
(-81)-36=-117

or if you have a calculator, just punch the equation in.
