The number after the "e" indicates how many powers of 10. In E notation the "times 10 raised to a power" is replaced with the letter e in either uppercase or lowercase. E notation is the same as scientific notation where a decimal number between 1 and 10 is multiplied by 10 raised to some power. In this example scientific notation calculation we're solving 1.225 × 10 5 + 3.655 × 10 3:ġ.225 × 10 5 + 3.655 × 10 3 = 1.26155 x 10 5 E NotationĮ notation is also known as exponential notation. Very small numbers are converted to an equivalent decimal number between 1 and 10, multiplied by 10 raised to some negative power. In scientific notation a large number is converted to an equivalent decimal number between 1 and 10, multiplied by 10 raised to some power. The answers are formatted in scientific notation and E notation.ġ22500 + 3655 = 1.26155 x 10 5 Scientific Notation Note that the inputs are standard notation numbers. Click on the link and then refer to the calculator above. This example calculation solves the addition problem 122500 + 3655. Standard notation is the usual way to write numbers, with or without commas and decimals. In each example the input forms are different, but they all produce the same answers in scientific notation and E notation. Use the links below to load a sample calculation into the calculator. If you do not mark the check box, answers may contain more digits than are signficant.Ĭaution: See note regarding significant figures calculations. If you mark the check box the calculator automatically determines the number of significant figures in the answer. You can also do operations on whole numbers, integers, and decimal numbers and get answers in scientific notation.
Answers are provided in three formats: scientific notation, E notation and engineering notation. Use this calculator to add, subtract, multiply and divide numbers in scientific notation, E notation or engineering notation.
