Adding decimal numbers is very much like adding numbers without decimal points. You add each column of numbers, starting with the rightmost column. If you have to “carry 1″, that goes into the next column on the left.
The trick with adding numbers with decimal points is to make sure that the decimal point is in the correct place in your answer. A good tip is to follow the point down and put it in the answer box first, even before starting the sum.
These decimal additions don’t require you to do any carrying and are relatively easy.
