Question

How do you do simplify this -9 -11

Answer 1

Answer:

-9 + -11=-20

Step-by-step explanation:

Since subtracting is the same as addition of the oppositie, just putting a negative symbol is easier because you are only working with negative numbers, instead of one negative and one positive.

Did that help?

Answer 2

Answer:

-20

Step-by-step explanation:

it’s just solving it, nothing special

-9+-11

(I made it addition ti make it easier, why, because if there’s a problem that doesn’t make sense right away make it addition, to make it addition just make the signs opposite, Ex: -3-5, we keep -3 and make the negative sign before the 5 into addition and now to make that equal we turn the now positive 5 into negative 5 so final result is -3+-5 which is much easier and you’ll get -8.
