How Do You Calculate a Decimal Number
We can add decimals, subtract, multiply and divide decimals. A column method is used in order to keep the decimal point in line. The example below shows 892.01 + 17.99. The answer is 910.00. 40.87 - 9.777, the answer is 31.093. Adding and subtracting decimals is the same as adding and subtracting whole numbers. The tens may be carried over to the next column. To multiply decimals we multiply each number by a power of ten. Once we get the sum we divide by a power of 10. To work out 0.09 multiplied by 1.2, we multiply 0.09 by 100 and 1.2 by 10. Once we establish the answer as 108 we divide it by 1000. The final answer is 0.108.
