Imagine you have 312 pieces of candy, and you want to give 194 of them to your friends. To find out how many you have left, we do a math takeaway called subtraction!
We write it down like a tower, lining up the numbers from right to left:
Let's solve it together, step-by-step, starting from the Ones room on the far right:
Step 1: The Ones Room (2 - 4)
- You have 2 candies, but your friend wants 4. Oh no, you don't have enough!
- So, you knock on your neighbor's door in the Tens room.
- The neighbor has 1 ten and kindly lends it to you. Now, the Tens room has 0 left.
- You bring that ten back to your room. Your 2 magically turns into 12!
- Now you can do it: 12 minus 4 is 8. Write 8 at the bottom.
Step 2: The Tens Room (0 - 9)
- Now look at the middle room. You have 0 left, but your friend wants 9.
- Time to knock on the next door—the Hundreds room!
- The Hundreds room has 3 hundreds. They lend you one, leaving themselves with 2.
- Your 0 magically turns into 10!
- Now you can do it: 10 minus 9 is 1. Write 1 at the bottom.
Step 3: The Hundreds Room (2 - 1)
- Finally, look at the last room on the left. You have 2 hundreds left, and you give away 1.
- 2 minus 1 is 1. Write 1 at the bottom.
The Grand Total
Look at the numbers you wrote at the bottom: 1, 1, and 8.
Put them together, and your answer is 118! You have 118 candies left. 🎉
