Can someone give me the answer and how you work this? -5 - (-10) = ?

5

Step-by-step explanation:

-5 - (-10)

Here we have to use sign of multiplication rule.

negative * negative = positive

that is, -(-) = +

We use this rule and simplify.

- (-10) = + 10

Therefore, -5 + 10

When we have different sign of the numbers, we have to subtract from greatest to least number, then put the largest number sign in the answer.

-5 + 10 = + 5

Hence, the answer is 5

Hope this is will help you.

Thank you.
