Scientific Notation
Add, subtract, multiply and divide numbers written as a · 10ⁿ, with a normalised answer and a step-by-step solution.
Scientific notation writes a number as a · 10n, where 1 ≤ |a| < 10.
Rules
a · 10m · b · 10k = ab · 10m+k
a · 10m : b · 10k = (a/b) · 10m−k
To add or subtract, first bring the numbers to the same exponent.
