How do you multiply bigger numbers, such as 2,000X700=?
First thing you want to do in line your numbers up. You want the big number on top and the little number on bottom, so it's much easier to solve.

2,000
X 700
-------------------

Then you want to know your Multiplication Table by heart, it will be much easier to solve these types of problems.

Start from the 2nd row to the very end of the number, So 700, start with the last 0, which is 700<---- That zero. You need to multiply that very by all the top numbers. As in 2,000, multiply it by all the zeros in order, from left to right and the 2 also. Now time for the next zero, 2,00<--0 We need to put One zero down before we multiply. Then multiply that zero by all the top numbers in order. Then the last number on the bottom row, which is the 7 in 700, is going to be multiplied by all the top numbers in order, but first you need to put down two ZEROS before you multiply. Now that you have all the numbers multiplied you add all the numbers up. If you have a calculator to check your work go ahead and check it.
