Problem 13
Question
Perform the indicated subtraction. $$-13-(-2)$$
Step-by-Step Solution
Verified Answer
\(-13 - (-2) = -11\}
1Step 1: 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.
2Step 2: Rewrite the expression using the axiom
This means the operation can be rewritten as: \(-13 - (-2)\) equivalent to \(-13 + 2\)
3Step 3: Perform the addition
When we perform the addition, we get: \(-13 + 2 = -11\)
