Double your tens digit to get your ones digits?
That means multiply it by 2. If your tens digit is 3, your ones digit is 6.
How do you multiply 2 digit numbers times 2 digit numbers?
You line them up and down and then multiply the first ones up and down on the right. then you do the diagonally ones and then you put a zero on the bottom right. then you go to the second number on the right and do the one diagonally and then the on up and down. then you add the two together and you have your answer. example:

How are you using the distributive property when you multiply one 2 digit number by another?
When you multiply a two digit number by another, you use the distributive property because you basically are taking the tens digits times both the other tens digit and the ones digit, then the ones digit times both the other tens and other ones digits. That sounds confusing, I know, but I'll explain. If you're taking 12 times 25, you are basically doing the problem (10+2) x (20+5). You take ten times twenty, then ten times five, then two times twenty, then two times five, and add them all together.
