How to Dividing Decimals
Description
A detailed tutorial on how to divide decimals. Step by step tutorial including several examples of dividing decimals for reference. It is a requirement to know how to divide decimals for all math classes.
Overview
Decimals are really no different from regular numbers when you perform operations on them, but sometimes the numbers in the decimal places can be a little tricky to figure out. The operation we will be talking about is division. With division, you set it up just like any long division problem. Move the decimal over to the right on the divisor so that there is no decimal, and then you must move the decimal point over exactly that many spaces on the dividend. Then solve it just like you would any other division problem, and don’t forget about the decimal point.

How to Multiply Decimals
Description
A detailed tutorial on how to multiply decimals. Step by step tutorial including several examples of multiplying decimals for reference. It is a requirement to know how to multiply decimals for all math classes.
Overview
Decimals are really no different from regular numbers when you perform operations on them, but sometimes the numbers in the decimal places can be a little tricky to figure out. The operation we will be talking about is multiplication. Normally, when performing an operation on decimals, you match up the decimal points. However, in multiplication you pretend that the decimal points don’t exist. You multiply as you normally would. However, you do need a decimal point in your final answer. You you need to perform a second operation. Count how many decimal places are in your first decimal, and then count how many there are in your second decimal. Add them together. When you get your final answer, count that many numbers (starting from the right) and then put down your decimal point that many places over.

How to Subtract Decimals
Description
A detailed tutorial on how to subtract decimals. Step by step tutorial including several examples of subtracting decimals for reference. It is a requirement to know how to subtract decimals for all math classes.
Overview
Decimals are really no different from regular numbers when you perform operations on them, but sometimes the numbers in the decimal places can be a little tricky to figure out. The operation we will be talking about is subtraction. The most important thing to remember when doing anything with decimals is to match up the decimal points and add zeros onto the end if you need to. Then just subtract like you normally would, and remember to put your decimal point back in the right place.

How to Add Decimals
Description
A detailed tutorial on how to add decimals. Step by step tutorial including several examples of adding decimals for reference. It is a requirement to know how to add decimals for all math classes.
Overview
Decimals are really no different from regular numbers when you perform operations on them, but sometimes the numbers in the decimal places can be tricky to figure out. The operation we will be talking about is addition. The most important thing to remember when doing anything with decimals is to match up the decimal points and add zeros on the end if you need to. Then just add like you normally would, and remember to put your decimal point back in the right place.
