Worked Example

Step-by-Step

Let's say you want to buy some laddoos for a small celebration. You ask the shopkeeper for a dozen laddoos. --- A 'dozen' means twelve. --- So, the shopkeeper will give you 12 laddoos. --- If you then eat 2 laddoos, you will have 12 - 2 = 10 laddoos left. --- If your friend gives you 2 more, you will have 10 + 2 = 12 laddoos again. So, twelve laddoos is the quantity you started with.
