what multiplication fact can you double to find 4X7?

4 x 7 is double 2 x 7, if that is what you mean.

This question is stupid. The answer is go jump off a cliff and then double it

4 x 7 is double 2 x 7

2+7

4x7

How can I multiply 20x9 faster then how I did before?

Hey, So I was wondering if I can find a faster way on how to multiply and make a sentence with it.
