How to Subtract Decimals Easily

Subtracting decimals can be tricky, but here are some simple steps to help you do it right!

1. Line Up the Decimals: First, make sure the decimal points are lined up straight. This helps you see which numbers you are subtracting more clearly.

2. Add Zeros If Needed: Sometimes, you might need to add zeros to make the numbers the same length. For example, $3.5$ can become $3.50$.

3. Think of Them as Whole Numbers: Next, you can ignore the decimals for a moment. Just think of the numbers as whole numbers. For instance, $4.85 - 2.3$ changes to $485 - 230$.

4. Round the Answer: Finally, when you get your answer, round it to how many numbers you need after the decimal. For example, if your answer is $2.55$, rounded to one decimal place, it becomes $2.6$.

By using these tips, you can subtract decimals better and faster!
