Decimals

When you add or subtract decimals, it is important to keep your decimals lined up with one another. When you add or subtract, make sure you are keeping your place value columns straight. Don't forget to bring that decimal point down to the final answer.

Remember, when multiplying decimals: When it is time to divide decimals, it is important that you aim for exact answers. You no longer want final answers that include remainders. Decimal answers allow you to have exact responses to division questions. When dividing decimals, you will have total success with the traditional, long division algorithm. If you cannot remember your steps for long division, try to recall the following acronym:
 * 1) Multiply like you would as if the decimals were not there. You can use traditional multiplication, partial products, or the lattice method.
 * 2) Place the decimal in the final answer by counting the total number of decimal places in the factors you are multiplying

 * Don't forget to put your decimal on the bridge before you start dividing.**
 * If you are dividing decimals by decimals, make sure you move the decimal in the divisor all the way to the right AND move the decimal in the dividend as many places as you moved the divisor decimal.
 * If you still have a remainder when you have brought down all of the digits in the dividend, add a zero and bring it down. Then continue dividing.**
 * Use compatible numbers when trying to divide each step.
