5Basic Math Concepts logarithms
The logarithm of a number is the exponent to
which 10 must be raised to equal that
number. e.g. log 100 2, because 100 102

7Basic Math Concepts antilogs
The antilogarithm of a number is the value that
results when 10 is raised by that number (becomes
the exponent). e.g. antilog 2 100, because 102
