The zeros at the end of a number are known as trailing zeros.
For example
Some Examples: Multiply 50 × 3; Multiply 200 × 6; Multiply 9 × 10,000
Multiply 70 × 6
Step 1:
Here we multiply 7 × 6 first
7 × 6 = 42
70 × 6 = 42__
Step 2:
Then we write a 0 at the end.
70 × 6 = 420
Multiply 600 × 4
Step 1:
Here we multiply 6 × 4 first
6 × 4 = 42
600 × 4 = 24__
Step 2:
Then we write two zeros at the end.
600 × 4 = 2400
