2 • (3 • 7) and (2 • 3) • 7 = ?

First one is 42 and the second one is 48.

Step-by-step explanation:

Start with parentheses. I'll use the first one as an example. 3 x 7 is 21. Now that the parentheses are done, multiply it by whatever's left. 21 x 2, that's 42. For the other one, 2 x 3 is 6, x 7, is 48. Have a good day :)

the first one is 42 because you do 3x7 and then multiply it by 2

3 x 7 = 21        21 x 2 =42

Step-by-step explanation:

the second one is 42 as well because 2x3 and multiply that by 7

2 x 3 = 6            6 x 7 = 42
