**Multiplication of 3 - digit numbers by 1-digit number:**

Ex: Multiply 498 by 3.

__Step - 1:__Multiply 8 ones by 3.

8 ones x 3 = 24 ones = 2 tens + 4 ones

write 4 in the ones place.

Carry 2 tens to the tens place.

__Step - 2:__ Multiply 9 tens by 3.

9 tens \[\times \] 3 = 27 tens

= 20 tens + 7 tens

= 2 hundreds + 7 tens

Carry 2 hundreds to the hundreds place.

Add the carried 2 tens to 7 tens.

So 7 tens + 2 tens = 9 tens,

write 9 in the tens place

__Step - 3:__ Multiply 4 hundreds by 3.

hundreds x 3 = 12 hundreds.

Add the carried 2 hundreds to 12 hundreds.

So, 12 hundreds + 2 hundreds = 14 hundreds,

write 14 in hundreds place

**Multiplication by TENS and HUNDREDS:**

5 \[\times \] 10 = 5 \[\times \]1 ten = 5 tens = 50

7\[\times \] 30 = 7 \[\times \] 3 tens = 21 tens = 210

15 x 60 = 15 \[\times \] 6 tens = 90 tens = 900

8\[\times \]100=8\[\times \] 1 hundred = 8 hundreds = 800

9 \[\times \] 400 = 9 \[\times \] 4 hundreds = 36 hundreds = 3600

**Multiplication by 2-digit numbers:**

Ex: Multiply 36 by 25
