Notes for Session 3, Part B


Note 1

When you use logarithms to multiply numbers with the same base that each contain exponents, you essentially reduce a multiplication problem to an addition problem. This is not so important now, but before the age of calculators and computers, it saved hours of work. Similarly, writing numbers in scientific notation allows us to estimate the magnitude of the result of a computation.
