## The Best Math help online

Math help online can support pupils to understand the material and improve their grades. To solve a factorial, simply multiply the given number by every number below it until you reach one. So, to solve 5!, you would multiply 5 by 4, then 3, then 2, and then 1. The answer would be 120. It is important to start with the given number and work your way down, rather than starting with one and working your way up. This is because the factorial operation is not commutative - that is, 5! is not the same as 1 x 2 x 3 x 4 x 5. When solving factorials, always start with the given number and work your way down to one.

Interval notation is a method of representing a set of numbers using Intervals. Interval notation solver is a online tool that helps you to solve the problems in Interval Notation. It shows the work by using the properties of Intervals, so you can understand the steps involved in solving the problem. You can also use this tool to check your answers.

Solving for a side in a right triangle can be done using the Pythagorean theorem. This theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. This theorem can be represented by the equation: a^2+b^2=c^2. In this equation, c is the hypotenuse and a and b are the other two sides. To solve for a side, one would rearrange this equation to isolate the desired variable. For example, to solve for c, one would rearrange the equation to get c^2=a^2+b^2. To solve for a, one would rearrange the equation to get a^2=c^2-b^2. Once the equation is rearranged, one can then use basic algebraic techniques to solve for the desired variable. In this way, the Pythagorean theorem can be used to solve for any side in a right triangle.
