Scientific Notation is like a shortcut for big or small numbers. Let's understand it with an example: 4,500,000,000.

Multiply 4.5 by 10^9. Combine the powers of 10: 4.5 * 10 * 10 * 10 * 10 * 10 * 10 * 10 * 10 = 4.5 * 10^9.

Divide 4.5 by 10^5. Subtract the powers of 10: 4.5 ÷ 10 ÷ 10 ÷ 10 ÷ 10 ÷ 10 = 4.5 * 10^(-5).

Add 4.5 * 10^9 and 3.2 * 10^8. Keep the power of 10 the same: (4.5 + 0.32) * 10^9.

Subtract 4.5 * 10^9 from 6.7 * 10^9. Keep the power of 10 unchanged: (6.7 - 4.5) * 10^9.
