Simple Example

Quick Example

Imagine you have 49 laddoos in a box. That means you have four groups of ten laddoos, and then nine more laddoos left over. It's a specific quantity, not just a random number.

Worked Example

Step-by-Step

Let's say you are counting money. You have 4 notes of 10 rupees each, and 9 coins of 1 rupee each.
---Step 1: Count the value of the 10-rupee notes. 4 notes x 10 rupees/note = 40 rupees.
---Step 2: Count the value of the 1-rupee coins. 9 coins x 1 rupee/coin = 9 rupees.
---Step 3: Add the values from Step 1 and Step 2. 40 rupees + 9 rupees = 49 rupees.
---So, the total amount of money you have is 49 rupees.

MISTAKE: Confusing forty-nine (49) with ninety-four (94) | CORRECTION: Always remember the place value: 'forty' means 4 tens, 'ninety' means 9 tens.
