![]() Each time you divide by 10, the exponent decreases by 1 and the decimal point moves one place to the left. The table shows the relationship between several powers of 10. Scientific Notation Calculator to add, subtract, multiply and divide numbers in scientific notation or E notation. Powers of 10 can be used to read and write very large and very small numbers, such as the masses of atomic particles. Note that we do not remove the trailing 0 because it was originally to the right of the decimal and is therefore a significant figure.The number 0.000380 converted to standard form is 3.80 x 10 -4.We moved the decimal to the right so b is negative.Move the decimal 4 places to the right and remove leading zeros to get 3.80.The number 459,608 converted to standard form is 4.59608 x 10 5Įxample: Convert 0.000380 to Standard Form.We moved the decimal to the left so b is positive.Move the decimal 5 places to the left to get 4.59608.Remove trailing 0's only if they were to the left of the decimal point.Įxample: Convert 459,608 to Standard Form.In other words, in scientific notation, a number is written as axx10n, where 1< 10. b is an integer and is the power of 10 required so that the product of the multiplication in standard form equals the original number.
a is a number whose absolute value is a decimal number greater than or equal to 1, and less than 10:.Standard form is like scientific notation where a number is represented as a decimal number times a power of 10. Written in standard form this number is equivalent to 6.71 x 10 8. Standard form is like scientific notation and is typically used in science and engineering.Ī number is written in standard form when it is represented as a decimal number times a power of 10.Īs an example, consider the speed of light which travels at about 671,000,000 miles per hour. It is often used for very large or very small numbers. Standard
