Simple Addition and Subtraction with Money


In Class 2 Maths, an important topic is to learn how to handle money using simple addition and subtraction. Money is a part of our daily lives. When you buy something, you use money. Let's learn how to do simple addition and subtraction with money using easy examples.

Understanding money

Before we start adding and subtracting, let's first understand money. Money can be in the form of coins and bills. In many countries, coins are 1 cent, 5 cents, 10 cents, 25 cents, and sometimes others, while bills can include $1, $5, $10, $20, etc.

Visual example: coins and their value

1 cent 5 cents 10 cents 25 cents

Adding money

Adding money is like adding numbers, but we have to maintain the units. Let's start with a simple addition. Imagine you have two coins: a 5-cent coin and a 10-cent coin. If you add these two coins together, how much money will you have?

5 cents + 10 cents = 15 cents

You have a total of 15 cents.

Visual example: adding coins

Here is how you can view the coin addition visualization:

5¢ 10¢ 15¢

Subtract money

Subtracting money means taking some money out of what you have. Let's say you have 20 cents and you want to buy a 15 cent sticker. How much money will you have left?

20 cents - 15 cents = 5 cents

After purchasing the sticker you will be left with 5 cents.

Visual example: subtracting coins

Subtracting coins can be shown visually as follows:

20¢ 15¢ 5¢

Working with large volumes

Now, let's add and subtract larger amounts, like dollars. Imagine you have $5 and you want to buy two things. The first thing costs $2 and the second thing costs $1. How much money will you have left after buying both things?

First, add the cost of the two items: $2 + $1 = $3 Then, subtract the total cost from the money you have: $5 - $3 = $2

You'll be left with $2.

Example: Buying things

Suppose you have $10 and you want to buy a book for $8 and an ice cream for $1. How much money will you have left?

First, add the cost of the book and ice cream: $8 + $1 = $9 Now, subtract the total from what you have: $10 - $9 = $1

After purchasing both items you will have $1 left.

Simultaneous use of coins and notes

Sometimes, you'll need to use both coins and bills to pay for things. Let's look at an example:

You have $4.50, made up of 4 dollar bills and 2 quarters (each quarter is worth 50 cents). If you buy something for $3.25, how much money will you have left?

First, calculate how much you are spending in total: $3 (from the bills) + 25 cents (from the coins) = $3.25 Now, subtract from what you have: ($4 + 50 cents) - $3.25 = $1.25

You will be left with $1.25.

More practice problems

Try solving these problems to practice adding and subtracting money:

  • If you have 30 cents and you find a 10-cent coin, how much money do you now have?
  • You decide to buy 45 cents worth of candy for a dollar. How much change will you get?
  • You want to buy two toys. One is $3 and the other is $4. How much money will you spend in total?
  • You have $5 and you spend $2.75 on a movie ticket. How much money do you have left now?

Conclusion

Learning how to add and subtract money is very useful in real life. Whether you're buying your favorite toy or saving money, you'll use these skills. Practice as much as you can, and soon you'll become very good at handling money and making smart shopping decisions.
