Question

The sum of two numbers is –11. The difference of the two numbers is –7. What is the product of the two numbers?

Answer 1

18

Explanation:

According to the numbers the both numbers have to be negative

subtracting a negative will be the same as addition and so thats why the difference is bigger.

now its time for guess and check.

-6+-5

-11

but -6-(-5)=-1

so lets try

-9+(-2)=-11

-9-(-2)=-7

yay

so the product is

(-9)*(-2)=18
