To add the two decimals together
A simple trick with multiplying decimal numbers is to remove the decimals, multiply the two numbers, then add the decimals back in. The number of decimals you add back in is the total number of decimal places. For example, the stated problem has 1 decimal places in 2.1 and 2 decimal places in 5.01. So first we do the following: 21x501=10521 Now we add 1+2=3 decimal places into the result above: 10.521 That's the answer.
Well, technically, addition and subtraction are opposites. if you add two numbers together, then you take one and put the other with it. if you subtract two numbers, you take one away from the other. if you are adding or subtracting decimals, then make sure that the decimals are lined up. Fractions have some different rules.
