Question

How -15 + 8 gives me 7 ????????

Answer 1

It gives you -7

Explanation:

Think of the problem as 8 - 15, because 8 is a smaller number and 15 is bigger, you'll get a negative number.

The next step is use the rule**a-b = -(b-a)**which is - (15 - 8)

Then when you simplify it, it will be - (15 - 8)= - 7**(which is the answer)

Hope this helps:)

Answer 2

it doesn’t give you 7
it gives you -7
because when you add 8 to negative 15, you’re just basically subtracting it to give you -7
