Imagine you are counting your collection of cricket cards. If you have 179 cards and then your friend gives you one more, you will now have 180 cricket cards. It's a way to show how many items you have in total.

Worked Example

Step-by-Step

Let's say you have 3 boxes, and each box contains 60 ladoos for a festival.

1. First, identify how many boxes you have: 3 boxes.
---
2. Next, identify how many ladoos are in each box: 60 ladoos.
---
3. To find the total number of ladoos, you multiply the number of boxes by the ladoos per box: 3 x 60.
---
4. Multiply 3 by 6: This gives 18.
---
5. Add the zero back from 60: So, 18 followed by 0 is 180.
---
Answer: You have a total of 180 ladoos.

Why It Matters

Common Mistakes

MISTAKE: Confusing 180 with 108 or 801 | CORRECTION: Always pay attention to the order of digits. 180 has 1 hundred, 8 tens, and 0 ones.

MISTAKE: Thinking 180 is an odd number | CORRECTION: An even number can be divided by 2 without any remainder. Since 180 / 2 = 90, it is an even number.

MISTAKE: Not understanding its place value (e.g., calling 180 'one eight zero') | CORRECTION: It's 'one hundred eighty'. The '1' is in the hundreds place, '8' in the tens place, and '0' in the ones place.
