Understanding Multiplication by 2
Multiplication by 2, also known as doubling, is one of the basic arithmetic operations. It means adding a number to itself. For example, 3 multiplied by 2 (or 3 times 2) is the same as 3 + 3, which equals 6.
Formula: If you have a number 'n', multiplying it by 2 can be represented as: 2 * n = n + n
Examples:
- 2 * 2 = 4 (which is 2 + 2)
- 5 * 2 = 10 (which is 5 + 5)
- 9 * 2 = 18 (which is 9 + 9)
This tool helps you quickly calculate and visualize the result of multiplying any single-digit number by 2, making it a fun and easy way to learn basic multiplication!
