Decimal Addition

To add decimals, you must write one above the other with their decimal points lined up, like this: look above.
What I learned this week, is simple steps to remember when adding decimals. First, you need to write down the numbers, one under the other, with the decimal points lined up. Next, put in zeros so the numbers have the same lenth. Last, add normally, remembering to put the decimal point in the answer.

Where one decimal doesn't have digits that the other one does, you put in zeroes, like this: look above.

Now, it's easy! You just add the two numbers as you would two whole numbers, with carries if necessary, but you keep track of where the decimal point goes and put it in the result right under the decimal points in the two numbers being added, like this: look above.
