Problem 26 - Introductory Algebra for College Students

Question

Perform the indicated subtraction. $$0-(-15)$$

Step-by-Step Solution

Answer

The solution for 0 - (-15) is 15

Step 1: Interpret the problem

The problem requires the subtraction of a negative number from zero. Since subtracting a number is equivalent to adding its opposite, one needs to realize that this operation actually translates to addition.

Step 2: Apply the rule for subtracting a negative number

Instead of performing 0 - (-15), the problem becomes equivalent to 0 + 15, given that subtracting a negative number equates to adding its positive counterpart.

Step 3: Perform the addition

Adding zero to any number does not change the original number's value. Thus, 0 + 15 equals 15.
