The online Scientific Notation Calculator is used to perform addition, subtraction, multiplication and division calculations in scientific notation.

## Scientific Notation

Scientific notation (also called standard form or exponential notation) is a way of writing numbers that accommodates values too large or small to be conveniently written in standard decimal notation.

In scientific notation all numbers are written like this:

a × 10^{b}

where the exponent b is an integer, and the coefficient a is any real number (called the significand or mantissa).

## E Notation

E notation is a type of scientific notation in which the phrase "times 10 to the power of" is replaced by the letter E or e; for example, 1.2 × 10^{5} is written as 1.2E+5 or 1.2e5 and 7.4 × 10^{-8} is written as 7.4E-8.
