We have covered these topics briefly below. For a detailed explanation of these topics, students can register on the Extramarks website and get full access to our NCERT Solutions for Class 4 Mathematics Chapter 6.

Properties of multiplication

One can multiply a one-digit or two-digit number by a one-digit or two-digit number. One is aware that 5 × 10 equals 50.

• Whenever any two or more numbers are multiplied, the order in which it multiplies them does not matter. The product remains the same.

Example: 2 × 5 = 10; 5 × 2 = 10. Therefore, whichever way numbers are multiplied, the answer remains the same.

• Any number multiplied by 0, the answer is always 0

Example: 3 × 0=0

• Any number multiplied by 1, the result or the product is the number itself.

Example: 8 × 1 = 8; 1 × 6 = 6; 1 × 1 = 1

• When three numbers are multiplied, they can be grouped in any order. The product is always the same.

Example: 23 × 18 × 38 = 15732, 18 × 23 × 38 = 15,732

Refer to Extramarks NCERT Solutions for Class 4 Mathematics Chapter 6 for more examples that will help students understand the detailed steps involved in solving multiplication questions.

### Different methods of multiplication

The unitary method is a method of solving a problem by first finding the value of a single unit from a given multiple, then finding the necessary value by multiplying the single unit value.

Example: 9 x 20 = 180

Step 1: First 9 is multiplied by 2 to get result 18

Step 2: Then add a 0 besides 18 to make it 180

Mental method: 9 times 2 is 18, so 9 times 20 is 180.

Let's see an example:

Vicky goes to a shop to buy chocolate. One chocolate costs Rs. 40. He wants to buy 6 chocolates. So how much does he have to pay to the shopkeeper?

Solution: Cost of 1 chocolate = Rs. 40

Cost of 6 chocolates = Rs. (40 × 6) = Rs. 240

One must multiply Rs.40  six times to get the necessary unit.

Box method

It is an alternative method of multiplication.

Example: 14×32 = ?

We do it like this:

 10 4 30 30×10=300 30×4=120 2 10×2=20 2×4=8

Add the numbers in the box: 300+120+20+8 = 448

Many students find it difficult to understand the steps involved in the box method of multiplication. To make it easier to learn, we have included a lot of examples in our NCERT Solutions for Class 4 Mathematics Chapter 6.

### Rupee and paise

The currency in India is Rupee. Rupee can be used to purchase anything in India. Rupee cannot be used in any other country. The symbol of the Rupee is ₹. 1 Rupee = 100 Paise

### What are loans and Interest?

When a bank or any other financial organisation lends money to a person in exchange for a promise to repay the money in the future and charges them for the credit extended, this is called a loan. The borrower takes a loan from the lender for a specific period of time and later pays back the original amount taken along with  interest in a set number of days.

There are different types of loans like vehicle loans, home loans, education loans etc.

So, if Vicky borrows Rs. 500 from a bank, and he promises to pay back Rs.100 every month for 6 months. How much does he pay after 6 months?

Rs. 100 × 6 months = Rs. 600.

The person who borrows a loan must return the loan to the bank or the money lender in parts and some extra money in the form of interest

How much extra money Vicky is paying after 6 months? Vicky is paying Rs. 100 extra. This additional amount is called Interest.

The concepts of loans and interests are difficult to understand. Our NCERT Solutions for Class 4 Mathematics Chapter 6 covers a lot of real-life situations that will help young students better understand how loan and interest work.
