Exercises Numbers, fractions and percents

Example 1.43 from Prealgebra, 1.4 Multiply Whole Numbers

Multiply Whole Numbers: example 1.43

Multiply:

ⓐ $8 \cdot 7$
ⓑ $7 \cdot 8$

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

ⓐ $8 \cdot 7$

Multiply. $56$

ⓑ $7 \cdot 8$

Multiply. $56$

Changing the order of the factors does not change the product.

Your turn

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

Multiply:

ⓐ $9 \cdot 6$
ⓑ $6 \cdot 9$

How did it go?
