625 is larger than 613 so I only need a 5 3 digit, a 5 2 digit, a 5 digit and a units digit. Thus I will have a 4 digit, base 5 number. Thus I will have a 4 digit, base 5 number. Start with the 5 3 digit.... It can also be shown (and is quite intuitive) that for an arbitrary base, the units digit of any power will only depend on the units digit of the base itself - that is 2013^2013 has the same units digit as 3^2013.

**Base Ten Blocks Math Central**

How numbers in other bases work. In Arabic numbers (decimal, or base 10), there are 10 digits: 0,1,2,3,4,5,6,7,8,9. You need one digit each to count up to 9, but two digits for ten, and three digits for a hundred, which is ten times ten.... Use the base ten blocks to model a 2-digit by 2-digit multiplication equation. To show 25 x 13, we would create a model like the one shown. When we multiply 25 by 13, we essentially repeat the multiplication process four times: 3 x 5, 3 x 20, 10 x 5, and 10 x 20.
