Best Answer

12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 = 108

The explanation is very simple.

Since there is nine twelves you are technically repeating twelve nine times, and the operation for that equation would be multiplication. The equation would be-

12x9= 108

12+12+12+12+12+12+12+12+12 = ?

Instead of stringing out an addition like this , we say 12 x 9 ( There being '9' lots of '12')

Refer to your multiplication tables.

12 x 9 = 108

or

9 x 12 = 108
