Multiplying and dividing by 10,100, and 1,000

63x10 = 630 

 There's a thousand,hundred,tens,and ones column, so you put 6 in the tens column because there's 6 tens and the 3 goes in the ones column because there's 3 ones and you multiply it by 10 which makes the 63,630 so you then move the digits one to the left so the six is in the thousand column and the 3 is in the tens column and the 0 is in the ones column because there's 0 ones.
