how do you add,subtract,and multiply decimals? please don't put a link.
please guys i seriously need help. i have a DMR quiz tommorrow over this.
The only way I can help you is to refer you to a website that has graphics capabilities.
Certainly! I'd be happy to explain how to add, subtract, and multiply decimals without using any external resources. Here's a step-by-step guide for each operation:
1. Adding Decimals:
Start by lining up the decimal points of the numbers you want to add. If one number has fewer decimal places, you can add zeros to the end to make them equal.
Then, add the numbers as you would with whole numbers, from right to left, carrying any excess over to the next place value.
Finally, place the decimal point in the sum directly below the decimal point in the original numbers.
2. Subtracting Decimals:
Similar to addition, start by aligning the decimal points of the numbers.
If one number has fewer decimal places, add zeros at the end to make them equal.
Then, subtract the numbers as you would with whole numbers, from right to left, borrowing as needed.
Finally, place the decimal point in the difference directly below the decimal point in the original numbers.
3. Multiplying Decimals:
Ignore the decimal points initially and multiply the numbers as you would with whole numbers.
Count the total number of decimal places in both numbers.
Then, place the decimal point in the product so that it has the same total number of decimal places as the original numbers combined.
It's important to double-check your work by estimating and ensuring the decimal places are correctly positioned. Practice with different examples to gain confidence in performing these operations.
