## Multiplication by One digit Number

We have learnt multiplication of 3 digit numbers by 1 and 2 digit numbers. We will use same method for multiplication of 4 or 5 digit numbers by 1, 2 and 3 digit numbers without or with carrying. Few examples are given below.

Example 1. Multiply 2143 by 2

Solution. 2143 X 2 = 4286

So, the answer is 4286.

Example 2. Multiply 32132 by 3

Solution.
Multiply ones, then tens, then hundreds, then thousands and at last ten-thousands. So, the answer is 96396.

## Multiplication by Two Digit Number

Example 1. Multiply 85 by 24

Solution. 85 X 24 = 85 X (20 + 4)

= 85 x 20 + 85 X 4

= 1700 + 340

= 2040

Example 2. Multiply 286 by 32

Solution. 286 X 32 = 286 X (30 + 2)

= 286 X 30 + 286 X 2

= 8580 + 572

= 9152

Example 3. Multiply 2523 by 47

Solution. 2523 X 47 = 2523 X (40 + 7)

= 2523 X 40 + 2523 X 7

= 100920 + 17661

= 118581

Example 4. Multiply 2523 by 37

Solution.
Step 1. Step 2. Step 3. So, the answer is 93351.

## Multiplication by Three digit Number

Example 1. Multiply 234 by 243

Solution. 234 X 243 = 234 X (200 + 40 + 3)

= 234 X 200 + 234 X 40 + 234 X 3

= 46800 + 9360 + 702 = 56862

Example 2. Multiply 5342 X 245

Solution. 5342 X 245 = 5342 X (200 + 40 + 5)

= 5342 X 200 + 5342 X 40 + 5342 X 5

= 1068400 + 213680 + 26710

= 1308790

## Story Time Multiplication

In our day to day life we use concept of multiplication in many ways, few examples are shown below.

Example 1. A cycle costs \$ 185. Find the cost of 25 such chairs?

Solution. Cost of 1 cycle = \$ 185

Cost of 25 cycles = \$ 185 X 25 So, the cost of 25 cycles are \$ 4625.

Example 2. Each student was given 15 chocolates in a school. There are 1526 students in the school. How many total number of chocolates were distributed among all students?

Solution. Each student got chocolates = 15

Number of chocolates 1526 students will get = 1526 X 15 Total number of chocolates were distributed in the school are 22890.
