How to do scientific notation subtraction
Web17 de sept. de 2024 · To subtract numbers in exponential notation, you follow the same steps but subtract the coefficients. Here’s an example: 0.0743 – 0.0022. To perform the subtraction, follow these steps: Convert both numbers to the same power of 10. Subtract the coefficients. 7.43 – 0.22 = 7.21. Join your new coefficient to the shared power of 10.
