# Understanding Scientific Notation: A Clear Explanation of the Increase Calculation Increase = 7.9 × 10¹⁶ – 5.2 × 10¹⁶ = 2.7 × 10¹⁶ If you’ve come across a calculation like 7.9 × 10¹⁶ – 5.2 × 10¹⁶ = 2.7 × 10¹⁶, you’re encountering one of the most fundamental operations in scientific notation—and why it matters in science, engineering, and data analysis. ### What Is Scientific Notation? Scientific notation is a powerful way to represent very large or very small numbers using a simplified format: a × 10ⁿ Where: - 1 ≤ |a| < 10, meaning a is a number with one to nine significant digits (exactly 7.9 or 5.2 in this case), - n is an integer exponent indicating the number of places the decimal moves. For example, - 7.9 × 10¹⁶ means 7.9 × 10,000,000,000,000,000 (7.9 × ten trillion, to be precise), - 5.2 × 10¹⁶ means 5.2 × 10,000,000,000,000,000 (5.2 × ten trillion).
