I improved it because someone didn't include 9x11, and 9x12.

9x9=81

9x9=81
6,561 (i solved it by using this sentence: (9x9) x (9x9)= 81x81=6,561
9x9=81
9x9=81, so 900x900 = 810,000
9x9 = 81.
9=9x1 18=9x2 27=9x3 36=9x4 45=9x5 54=9x6 63=9x7 72=9x8 81=9x9 90=9x10
The meaning of "nine times nine is eighty one" is 9x9=81
You can make one. But, since you can multiply ones and tens separately, and add (i.e., use the common multiplication algorithm), it really isn't necessary to have a multiplication table beyond the range from 0x0 to 9x9.
It means to times a number by itself e.g. 9 squared = 9x9 = 81!
There are 2025 rectangles in a 9x9 grid.
11x8 - 9x9 = 7
