There are more than 10000 math symbols.A symbol for the set of rational numbers. The rational numbers are included in the real numbers , while themselves including the integers , which in turn include the natural numbers . In mathematics, a rational number is a number that can be expressed as the quotient or fraction of two integers, a numerator p and a non-zero denominator q. [1] In an “if-then” statement in math, the “then” part of the statement is the conclusion. It is the part of the statement that is the end result. In geometry, a proof is written in an if-then format.Example: Rearrange the volume of a box formula ( V = lwh) so that the width is the subject. Start with: V = lwh. divide both sides by h: V/h = lw. divide both sides by l: V/ (hl) = w. swap sides: w = V/ (hl) So if we want a box with a volume of 12, a length of 2, and a height of 2, we can calculate its width: w = V/ (hl)
