Hello dear children! Today, we’re going to learn something really exciting and useful — Addition! You’ve already learned how to add 3-digit numbers, right? Great job! Now, we’re going to level up and learn how to add 4-digit numbers — both with and without carrying. Don’t worry, I’ll be with you every step of the way!
What is Addition?
Addition means putting things together. When we add, we’re simply finding how many in total. Just like when you collect tamarind seeds after playing a game and count how many you got — that’s addition!
Real-Life Example: Shopping at the Store
Imagine you went to a shop and saw different items with price tags:
- A mobile costs ₹2454
- A calculator costs ₹324
Now you want to know how much money you’d need to buy both.
We add the numbers like this:
markdown
2454 (Cost of Mobile)
+ 324 (Cost of Calculator)
——-
2778 (Total)
So, you’d need ₹2778 in total!
Let’s Understand Addition Step-by-Step
Let’s take one more example. A housewife buys:
- A music player for ₹2420
- A wristwatch for ₹1349
Let’s add their prices together.
markdown
2420
+ 1349
——-
3769
That means she spent ₹3769 in total.
Always remember: Start adding from the units place, then move to tens, then hundreds, and finally thousands.
Addition with Carrying (Regrouping)
Sometimes when you add, the total in one column becomes more than 9, so you need to carry the extra value to the next place.
Let’s look at an example:
- Mixer = ₹3847
- Mobile = ₹2454
Let’s add:
markdown
3847
+ 2454
——-
6301
Here’s how we got that:
1️ Add units: 7 + 4 = 11 → write 1 and carry 1
2️Add tens: 4 + 5 = 9 → plus the carry = 10 → write 0 and carry 1
3️Add hundreds: 8 + 4 = 12 → plus 1 = 13 → write 3 and carry 1
4️ Add thousands: 3 + 2 = 5 → plus 1 = 6
So, total = ₹6301
Wasn’t that fun?
Adding in Your Head (Mental Math)
Sometimes, you don’t even need paper and pencil! You can add numbers in your mind by breaking them up.
For example:
328 + 241
Let’s split 241 into parts:
328 + 200 = 528
528 + 40 = 568
568 + 1 = 569
So, 328 + 241 = 569
Easy, right?
Let’s try a bigger one:
5347 + 2635
Break 2635 into 2000 + 600 + 30 + 5
yaml
5347 + 2000 = 7347
7347 + 600 = 7947
7947 + 30 = 7977
7977 + 5 = 7982
FAQs
Q: Do I always need to carry when adding 4-digit numbers?
A: No, only when the total in one place is 10 or more. Then we carry to the next place.
Q: What should I do first while adding?
A: Always start from the units place (the rightmost number).
Q: Can I add numbers without writing them down?
A: Yes! That’s called mental math. You can break numbers into parts and add them step by step in your mind.
Q: Why do we need to learn addition?
A: Because we use it every day — at shops, while cooking, or even counting your toys!
Q: I made a mistake while adding. What should I do?
A: That’s okay! Mistakes help you learn. Just check each step and try again. You’ll get it!
