Scientific notation (also referred to as scientific form, standard form or standard index form) is a way of expressing numbers that are too big or too small to be conveniently written in decimal form. It is commonly used by scientists, mathematicians and engineers, in part because it can simplify certain arithmetic operations.
Here are the steps to adding or subtracting numbers in scientific notation 1  : Determine the number by which to increase the smaller exponent by so it is equal to the larger exponent. 2  Increase the smaller exponent by this number and move the decimal point of the number with the smaller exponent to the left the same number of places. Add or subtract the new coefficients. If the answer is not in scientific notation (i.e. if the coefficient is not between 1 and 10 ) convert it to scientific notation.
