When you perform division, you can typically write down this operation in the following way:. Example: How many 2s do we multiply to get 8? Usually, once you get the math equation, you're fine; the actual math involved is often fairly simple. One other value of the factorial and one for which the standard definition above does not hold is that of zero factorial. (For functions to convert strings to floating point numbers (atof(), strtod(), etc. Mathematics is certainly a science in the broad sense of "systematic and formulated knowledge", but most people use "science" to refer only to the natural sciences. All of our examples have used whole number logarithms (like 2 or 3), but logarithms can have decimal values like 2.5, or 6.081, etc. Or try taking the quiz yourself—you might be surprised at how much you remember from your school days.
