using place vale to solve multiplication problems.

I was using multiplication to solve place value problems. I noticed that I was going over them a bit to fast and wasn't taking my time that's something I need to work on.

for example I did 17 x 5 = I broke up the 17 into 10 ans 7 and did 10 x 5 = 50 and 7 x 5 = 35 so 50 plus 35 = 85.

i realised i found this task easy and I don't need more practice.
