Question

2 • (3 • 7) and (2 • 3) • 7 = ?

Answer 1

First one is 42 and the second one is 48.

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 :)
