Chapter 2, starting on page 38, talks about operators. That's the
usual way you'd want to do arithmatic. You shouldn't use the bcmath
functions unless you need to deal with really, really big numbers.
If you need to multiply three numbers together, you can use the *
operator. For example:
$myProduct = 100 * 45 * 13;
