Multiplication

We are familiar with the process of multiplication. We have done the
multiplication of the smaller numbers but we do not deal with small

numbers in our day-to-day life. Here, we will learn how multiplication of
the larger numbers is done.

Multiplication of larger numbers is not different from the multiplication
of smaller numbers.

Example 9: Multiply 4325 by 234.

Solution: Also, it can be written as:

4 3 2 5 → Multiplicand 4 3 2 5

× 2 3 4 → Multiplier (200 + 30 + 4) × 2 3 4

1 7 3 0 0 ← (4325 × 4) 1 7 3 0 0

1 2 9 7 5 0 ← (4325 × 30) 1 2 9 7 5

+ 8 6 5 0 0 0 ← (4325 × 200) + 8 6 5 0

1 0 1 2 0 5 0 → Product 1 0 1 2 0 5 0

Lattice Method

Thus, 4325 × 234 = 1012050
