A perfect square-root chart lists the integer roots of numbers that have no fractional component. Multiplying these square roots by themselves results in designated perfect squares. For example, the square root of nine i... More » Math Exponents

In calculus, limits are used to discuss the behavior of a function and its graph. By designating a limit at a given x-value, a mathematician can describe how that function might approach a coordinate even if the function... More » Math Fractions & Percentages

A square root is the result of "unsquaring" a number, or the reversal of the process of squaring. The root is, as its name implies, a squared number reduced to its most basic form. More » Math Algebra
