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

it equals 72. just do 12 X 6
it equals 70
12 plus 9 equals 21.
12+12
12 + 10 + 11 equals 33
5 plus 25 equals 60. Need to solve for 5 plus 25 equals ?: 2 plus 10 equals 24 is equivalent to 2 × (1 plus 5) equals 2 × (12); and 3 plus 15 equals 36 is equivalent to 3 ×(1 plus 5) equals 3 × (12); thus 5 plus 25 equals ? is equivalent to 5 × (1 plus 5) equals 5 × (12); thus ? = 5 × 12 = 60.
yes. think of 6/12 plus 1/12. that is 7/12!
12 + 12 + 12 + 191 = 227
24
It is: 12 plus 22 = 34
Yes, 12 plus 12 does equal 24.
