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 Some examples are:
log10
 10 = 1,
since 101 = 10
log10 100 = 2,
since 102 = 100
log10 10000 = 4,
since 104 = 10000
log10 0
