Question

Simplify: -21-(-15)+(-9)-5

Answer 1

Answer:

-20

Step-by-step explanation:

We go in order of operations. Since there is no multiplication, division, exponents, or parentheses(the negative numbers in parentheses don't count), we start solving the operation from left to right.

-21-(-15) = -21+15 = -6

-6+-9=-15

-15-5=-20

Now we get our answer of -20.
