What is 9 x 7?

The multiplication of 9 by 7 gives 63. This can be understood by visualizing the problem as groups of 9, where you have 7 such groups. Therefore, if you add 9 a total of 7 times (9 + 9 + 9 + 9 + 9 + 9 + 9), you will arrive at 63.

Additionally, if you break it down further, you can think of 9 as 10 - 1. Thus, calculating 9 x 7 can also be done by first calculating 10 x 7, which is 70, and then subtracting 7 (which is 1 x 7). This gives you 70 - 7 = 63, confirming that the answer is indeed correct. Understanding multiplication as repeated addition or through regrouping helps solidify the concept.
