9 x 9 = 81
9 + 9 + 9 + 9 + 9 + 9 + 9 + 9 + 9 = 81
What this tells you is that if you added 9 to itself 9 times, you will get 81 as the total. Multiplication is just a fast way to add numbers. That is why it is best to memorize the multiplication facts, since you use them more and more as you go up the grades in school.
You are very smart, and your parents should be proud of you! Most children in the THIRD GRADE could not tell you what 9 x 9 is.
