Multiplication Methods

We can multiply numbers in two ways. The product remains the same in both.

1. In horizontal multiplication, we place the numbers next to each other with

a multiplication sign in between. The product is also written in the same
row. For example, 4 × 2 = 8

2. In vertical multiplication, we place the numbers one below the other with
a multiplication sign before the second number. The product is written
below the second number. For example,

T O

4 first number

× 2 second number

8 product
