The factorial of the number 0 is defined as 1 because there is only one possible permutation for a set of zero elements, namely the empty set. The combinatorial interpretation of the factorial function is the total numbe... More »

There are many different types of quadrilaterals: squares, rectangles, rhombuses, trapezoids, parallelograms and kites. A quadrilateral defined as a closed shape (polygon) that consists of exactly four straight lines. More »

How much weight a beam bridge can hold depends on the materials it is made of and the distance between its supports. Typically, a singular beam bridge is a maximum of 250 feet long, but several beam bridges can be combin... More »
