Exercises Expressions, exponents and radicals

Example 7.34 from Prealgebra, 7.4 Properties of Identity, Inverses, and Zero

Properties of Identity, Inverses, and Zero: example 7.34

Find the additive inverse of each expression: ⓐ $13$ ⓑ $- \frac{5}{8}$ ⓒ $0.6$ .

Work it out on paper first. Then open the solution one step at a time, and stop as soon as you can finish on your own.

Solution
To find the additive inverse, we find the opposite.
1. ⓐ The additive inverse of $13$ is its opposite, $−13 .$
2. ⓑ The additive inverse of $- \frac{5}{8}$ is its opposite, $\frac{5}{8} .$
3. ⓒ The additive inverse of $0.6$ is its opposite, $−0.6 .$

Your turn

The book's Try It right after this example: same idea, new numbers. Only the answer is given.

Find the additive inverse: ⓐ $18$ ⓑ $\frac{7}{9}$ ⓒ $1.2$ .
