The expression is missing from Step 1 is [-8 - 1] + (2 + 3). thus option C is the correct choice.

Usually, simplification involves proceeding with the pending operations in the expression.

Simplification usually involves making the expression simple and easy to use later.

WE have been given an expression;

[(-10+2)-1] + (2+3)

Since (-10+2) is the first parentheses, we solve and get -8

so it will turns [(-10+2)-1] + (2+3) into

(-8-1) + (2+3)

Now, solve for -8-1

-9 + 2 + 3

To check; (-10+2)= -8 -8-1 = -9

Therefore, the expression is missing from Step 1 is [-8 - 1] + (2 + 3). thus option C is the correct choice.
