Exercises Expressions, exponents and radicals

Example 7.36 from Prealgebra, 7.4 Properties of Identity, Inverses, and Zero

Properties of Identity, Inverses, and Zero: example 7.36

Simplify: ⓐ $−8 \cdot 0$ ⓑ $\frac{5}{12} \cdot 0$ ⓒ $0 (2.94)$ .

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

ⓐ

$−8 \cdot 0$

The product of any real number and 0 is 0. $0$

ⓑ

$\frac{5}{12} \cdot 0$

The product of any real number and 0 is 0. $0$

ⓒ

$0 (2.94)$

The product of any real number and 0 is 0. $0$

Your turn

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

Simplify: ⓐ $−14 \cdot 0$ ⓑ $0 \cdot \frac{2}{3}$ ⓒ $(16.5) \cdot 0 .$
