Here you will learn about decimal operations!
What are Decimal Opertations?
A decimal operation is a operation you do with a whole number and a decimal, or two decimals or more. You can do many things with decimal operations, like adding, subtracting, multiplying, and dividing decimals by whole numbers, or decimals by decimals.
Adding Decimal Operations.
Adding in decimal operations is simple. First, you just align the decimal point with the other decimal point. After this, you put down the decimal. Then you add as if the decimal wasn't there. When you get your answer, you just put a new decimal and then align it to the problem decimal. And there is how to add in a decimal operation.
Subtracting Decimal Operations.
Subtracting in a decimal operation is mostly the same as if you where adding, but you subtract. You first have to align the decimals. Then you must subtract as if the decimal wasn't there. When you get your answer, you will just put a new decimal that is aligned to the ones on the operation.
Multipling Decimal Operations.
Multipling in decimal operations is different from adding or subtracting in decimal operations. First of all, you DO NOT have to align the decimals, you just put the digits just as you would in a normal operation. You just multiply as if the decimal wasn't there. When you have your answer of the operation, you count the decimal spaces on the operation. Then, you just add the total of the decimal spaces to the answer. Then you have your answer.
Dividing Decimal Opertaions
To divide a decimal operation you first have to find if the digit outside of the house has a decimal. If it doesn't, you just put the digit inside of the house up, but if it does, you have to move the decimal to the end of the digit outside, and do the same spaces you did to the digit outside. Once you did that, you put the place where the decimal ended on the number inside the house up. Then you just divide normally and there you have it.
