BASIC Mathematical Operations

Most of the BASIC math operators are ones that require no introduction. The addition, subtraction, multplication and division operators are ones commonly used as shown below:
+ .... Addition: c = a + b
- .... Subtraction: c = a - b
* .... Multiplication: c = a * b
/ .... Division: c = a / b
BASIC can also use two other operators for INTEGER division. Integer division returns only whole number values. MOD or remainder division returns a value only if an integer division cannot divide a number evenly.
\ .... Integer division: c = a \ b
MOD .... Remainder division: c = a MOD b
There are also a couple of operators for exponential calculations. The exponetial operator is used to raise a number's value to a designated exponent of itself. The SQR function returns a number's Square Root. For other roots the exponential operator can be used with fractions such as 1 / 3 designating the cube root of a number.
^ .... Exponent: c = a ^ 2 + b ^ 2
SQR(n) .... Square root: c = SQR(a)

BASIC's Order of Operations
When a normal calculation is made BASIC works from left to right, but it does certain calculations in the following order:
1) Exponential and exponential Root calculations
2) Multiplication and Division calculations
