Question #288f0

Answer 1

27

Explanation:

Just for your own ease of use in life, it is recommended that you actually take the time and effort to memorize the "times tables" at least up to the 12's.
Basic math is essential to function well in modern life.

ALL multiplication is a 'short-hand' for repeated addition. "3 times 9" is literally just that - take '9', 3 times:
`9 + 9 + 9 = 27`

The beauty and utility of mathematics is that these combinations can then be manipulated more easily. `3 x 9 = 9 x 3` is much easier to use than re-writing the 'take '3', 9 times' version!
`3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 = 27`
