Answer 2

Answer:

20 times.

Step-by-step explanation:

I'll keep it basic.

While writing number in table for m,

while going from left right you'll encounter 11 twos (10 per column and 1 extra for 22's 2)

2, 12, 22, 32. . . 92

While running from top to bottom in the second column (20, 21, 22. . .29) we should have 10 twos too but since we have already counted 22, only 9 are left.

So the net sum = 11 +9 =20
