Multiplying Larger Numbers

Suppose we want to multiply 57 by 13. First we multiply 57 by 3 to get 171 .
Next we multiply 57 by 1..
1 is in the tens column so it really means 10. We have to put a 0 directly under the 1 in 171.
Now we can multiply 57 by 1 to get 57.
To finish up, add the two products
So 57 multiplyed by 13 is 741.
