Multiplication 63

Step 4: Multiply 3 thousands by 3. Th H T O

3 thousands × 3 = 9 thousands. 3 2 1 3
Write 9 under thousands column. × 3

Thus, 3213 × 3 = 9639
9 6 3 9
With Regrouping

Let us multiply 1753 by 5.

Arrange the numbers as per their place values and follow these steps:
Th H T O
Step 1: Multiply 3 ones by 5.
1
3 ones × 5 = 15 ones 1 7 5 3

15 ones = 10 ones + 5 ones = 1 ten + 5 ones × 5

Write 5 under ones column and carry over 1 ten to tens 5
column.
Th H T O
Step 2: Multiply 5 tens by 5. 2 1

5 tens × 5 = 25 tens 1 7 5 3

25 tens + 1 ten (carried over) = 26 tens × 5
26 tens = 20 tens + 6 tens = 2 hundreds + 6 tens 6 5

Write 6 under tens column and carry over 2 hundreds to hundreds column.

Step 3: Multiply 7 hundreds by 5. Th H T O

7 hundreds × 5 = 35 hundreds 3 2 1

35 hundreds + 2 hundreds (carried over) = 37 hundreds 1 7 5 3

37 hundreds = 30 hundreds + 7 hundreds × 5
= 3 thousands + 7 hundreds 7 6 5

Write 7 under hundreds column and carry over
3 thousands to thousands column.

Step 4: Multiply 1 thousand by 5. Th H T O
3 2 1
1 thousand × 5 = 5 thousands 1 7 5 3
5 thousands + 3 thousands (carried over) = 8 thousands × 5

Write 8 under thousands column. 8 7 6 5

Thus, 1753 × 5 = 8765
