Discover how fun learning can be with games and surprises!
Adding and subtracting decimals is just like adding and subtracting whole numbers—just don’t forget the decimal point!
Think of decimals like pieces of candy. If you have 1.5 candies and your friend gives you 2.3 more, you count all the candies together to see how sweet it gets! 🍬🍬
First comes the line-up, then comes the math…
Line up those decimal points! They’re like little soldiers standing tall in a row.
Write down your numbers carefully so the dots (decimal points) match perfectly.
Next, add or subtract just like normal numbers.
Remember: Addition means putting together. Subtraction means taking away.
Taking away means less, but adding means more!
Finally, bring the decimal point straight down into your answer—it’s like magic!
Problem: Add 4.7 + 2.9
Step 1: Line up the decimal points:
4.7
+2.9
----
Step 2: Add them like whole numbers:
Start from the right: 7 + 9 = 16. Write down 6 and carry over 1.
Then move left: 4 + 2 + 1 (carried over) = 7.
Bring the decimal point straight down!
Answer: 4.7 + 2.9 = 7.6 🎉
