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.
