Similarly, the Second Law says: the log of the ratio of two numbers is the difference of their logs Thus,
the use of these laws converts a problem of multiplication/division into a problem of addition/subtraction,
which are far easier to perform than multiplication/division That is why logarithms are so useful in
all numerical computations Logarithms to Base 10
Because number 10 is the base of writing numbers, it is very convenient to use logarithms to the base
10
