Money is a useful tool we use daily for buying items or paying for services.
We can perform math operations with money, including addition, subtraction, multiplication, and division, to manage our finances wisely. These operations help in finding totals, changes, calculating prices for several items, sharing money equally, and splitting bills.
Let’s dive into the topics covered:
What is Money?
Money is a medium we use to buy things or pay for services.
It comes in coins, notes, cards, and online payments.
For instance, in India, the coins and notes are 1 rupee, 2 rupees, 5 rupees, 10 rupees, 10, 20, 50, 100, 200, 500, and 2000 rupees.
Why Do We Need Money Operations?
Money operations help in finding the total amount, change, sharing money equally, calculating prices for multiple items, and splitting bills.
For example, when adding money, you might need to find the total cost of several items, like a toy and a book.
Adding Money
To add money, treat it like normal numbers with the rupee symbol and decimal point (for paise).
For example, if you buy a toy for 45.50 rupees and a coloring book for 25.75 rupees, the total cost is 71.25 rupees.
Subtracting Money
Subtract money like normal numbers with decimals.
For example, if you have 100 rupees and buy something for 65.30 rupees, you are left with 34.70 rupees.
Multiplying Money
Multiply money to find the total cost when buying multiple items of the same price.
For example, if a chocolate costs 12 rupees and you want five chocolates, the total cost is 60 rupees.
Dividing Money
Divide money to share it equally or split bills among people.
For example, if a prize of 600 rupees is to be shared among six winners, each winner gets 100 rupees.

Summary
Operation | What It Does | When to Use | Example
| Addition | Finds total | Buying many things | 50 + 30 = 80|
| Subtraction | Finds difference/change | Getting balance back | 100 – 75 = 25|
| Multiplication | Repeats same value | Buying multiple same items | 12 * 4 = 48|
| Division | Shares equally | Splitting a bill | 200 / 4 = 50|
Now, let’s practice:
1. A book costs 125 rupees.
You buy 3.
What is the total?
2. You had 1000 rupees.
You spent 275.50 rupees.
How much is left?
3. A candy costs 5 rupees.
How much for 8 candies?
4.You want to share 360 rupees among six friends.
How much for each?
