Chapter 1: Problem 13

Perform the indicated subtraction. $$-13-(-2)$$

Short Answer

Expert verified
\(-13 - (-2) = -11\}

Step by step solution

01

Understanding the axiom

The axiom of subtracting a negative can be understood as 'subtraction of a negative number equals addition of a positive number'. Hence, a minus outside and a minus inside brackets will become a plus.
02

Rewrite the expression using the axiom

This means the operation can be rewritten as: \(-13 - (-2)\) equivalent to \(-13 + 2\)
03

Perform the addition

When we perform the addition, we get: \(-13 + 2 = -11\)
