9+9 and 9+9+9+9+9

The multiplication fact (singular, not plural 'facts') that can be found is 7x9 = 63. Using the arrays, a 2x9 array (2 rows of 9 items) and 5x9 array (5 rows of 9 items) is 63: 2x9 = 18 5x9 = 45 18 + 45 = 63

They both cannot be

Absolutely. In fact, using loops to process arrays is one the most fundamental paradigms in programming.

2x2=4

multiplication fact means the truth

No. A multiplication fact contains two factors being multiplied, like 0x8 or 7x6.

There is only one number. The simplest multiplication fact is 3122111 x 0 = 0There is only one number. The simplest multiplication fact is 3122111 x 0 = 0There is only one number.
