### Basic Math Commands

DarkBASIC has several useful math commands; I will go over the basic ones here. Later in this chapter, I’ll explain the more advanced math commands.

#### Square Root

The SQRT command is short for “square root.” The square root of a number X is the value which, when multiplied by itself, results in the number X. The square root is the opposite of a number raised to the second power (N ^ 2). Consider an earlier example, 10×10 = 100. The square root of 100 is 10, or rather SQRT(100) = 10. Remember that this differs from exponents in general in that the square root only applies to a squared number. Here is an example:

```A = 100
B = SQRT(A)
PRINT "The square root of "; A; " is "; B; "."```

#### Absolute Value

The ABS command returns the absolute ...
