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.
