6 + 6 + 6 + 6 + 5 =29.
Multiplication is an easier form than addition when adding the same number over and over. For example . . . Addition: 6+6+6+6+6+6+6+6+6 = 56. You add 6 + 6 = 12, then you add 12 + 6 = 18, then you add 18 = 6 = 24, then you add 24 + 6 = 30, then you add . . . . . This is tedious and time wasting. Suppose there were 2 thousands 6's - it would take a long, long time to finish. If you use multiplication . . . 6 x 9 = 54 or 2,000 x 6 = 12,000 or to get really crazy, how about 6 x 9,537? You could add 9,537 6's, which would take a huge amount of time when you could simply multiply, instead: 6 x 9,537 = 55,222

You add negative 3. you can add -3 to nine to make it 6
If 5 X 6 = 30 OR 6+6+6+6+6=30 Because 5 stands for the amount of sixes you add together so if 5 X 6 = 30 then 6 X 6 would just add six to the 5 X 6 6 X 6 = 36 5 X 6 = 30 36 - 30 = 6 Because all you did was add six.
6 + 6 + 6 + 6 + 5 =29.
You need to add 6 - (-9) = 6 + 9 = 15.
22 + 19 + 6 + 14 = 61
Add 11 -6 + 11 = 5
You need to add 12.
Add
You will add -3 to 9 to make it 6.
6+6+6+6+6+6
17 - (-6) = 23 Therefore, the number you have to add to -6 to make 17 is 23.
