![]() ![]() ![]() By convention, the quotient is written such that there is only one non-zero digit to the left of the decimal. Divide the digits normally and subtract the exponents of the powers of 10. To divide numbers in scientific notation, separate the powers of 10 and digits. The digits are multiplied normally, and the exponents of the powers of 10 are added to determine the new power of 10 applied to the product of the digits. To multiply numbers in scientific notation, separate the powers of 10 and digits. Once the numbers are all written to the same power of 10, add each respective digit. To add and subtract in scientific notation, ensure that each number is converted to a number with the same power of 10. Scientific notation can simplify the process of computing basic arithmetic operations by hand. In scientific notation, numbers are written as a base, b, referred to as the significand, multiplied by 10 raised to an integer exponent, n, which is referred to as the order of magnitude:īelow are some examples of numbers written in decimal notation compared to scientific notation: Decimal notation It is commonly used in mathematics, engineering, and science, as it can help simplify arithmetic operations. Scientific notation is a way to express numbers in a form that makes numbers that are too small or too large more convenient to write and perform calculations with.
