So, the answer is 96396.

## Multiplication by Two Digit Number

**Example 1.** Multiply 85 by 24

**Solution.** 85 × 24 = 85 × (20 + 4)

= 85 × 20 + 85 × 4

= 1700 + 340

= 2040

**Example 2.** Multiply 286 by 32

**Solution.** 286 × 32 = 286 × (30 + 2)

= 286 × 30 + 286 × 2

= 8580 + 572

= 9152

**Example 3.** Multiply 2523 by 47

**Solution.** 2523 × 47 = 2523 × (40 + 7)

= 2523 × 40 + 2523 × 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 × 243 = 234 × (200 + 40 + 3)

= 234 × 200 + 234 × 40 + 234 × 3

= 46800 + 9360 + 702 = 56862

**Example 2.** Multiply 5342 X 245

**Solution.** 5342 × 245 = 5342 × (200 + 40 + 5)

= 5342 × 200 + 5342 × 40 + 5342 × 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.
