In Lesson 1, We’re going to learn how to subtract numbers, which is like magic for taking things away. Just like addition is about putting things together, subtraction is about taking things apart.
1. Taking Away: Subtraction helps us figure out how many things we have left when we take some away. Imagine you have 8 colorful blocks, and you give 3 to your friend. To find out how many blocks you have left, you subtract 3 from 8. So, 8 – 3 equals 5. You still have 5 blocks!
2. Using the Minus Sign: We use the minus sign (-) to show subtraction. It’s like a little line that tells us we’re taking away.
3. Story Problems: Subtraction helps us solve real-life problems too. For example, if you have 10 apples and you eat 2, you can use subtraction to see if you have 10 – 2, which equals 8 apples left.
4. Comparing Numbers: You can also use subtraction to compare numbers. If you have 7 candies and your friend has 5, you can subtract to see who has more. 7 – 5 equals 2, so you have 2 more candies than your friend.
Subtraction is a fantastic skill that helps you solve puzzles, share things, and understand how things change when you take them away. As you practice, you’ll become a subtraction superstar, ready to tackle even more exciting math adventures!
