Multiplying a number by 10 moves each digit one place to the left. For example, if you multiply 5 by 10, it becomes 50, and the digit '5' moves one place to the left, becoming '5' in the tens place.
In general, multiplying by 10^n (where n is a positive integer) moves each digit n places to the left. For example:
- Multiplying by 10 (10^1) moves each digit one place to the left (e.g., 123 becomes 1230).
- Multiplying by 100 (10^2) moves each digit two places to the left (e.g., 123 becomes 12300).
- Multiplying by 1000 (10^3) moves each digit three places to the left (e.g., 123 becomes 123000).
In essence, multiplying by 10 or its powers increases the value of the number by shifting the position of its digits to the left.
