Arithmetic Operators
Arithmetic operators are used to perform mathematical computations. They have numerical operands and return
numerical results. Since the char operators are technically bytes, they can be also used as unsigned operands in
arithmetic operations.
All arithmetic operators associate from left to right.

Division by Zero
If 0 (zero) is used explicitly as the second operand (i.e. x div 0), the compiler will report an error and will not generate
code.
But in case of implicit division by zero: x div y, where y is 0 (zero), the result will be the maximum integer (i.e 255, if
the result is byte type; 65536, if the result is word type, etc.).
Unary Arithmetic Operators
Operator - can be used as a prex unary operator to change sign of a signed value. Unary prex operator + can be
used, but it doesn’t affect data.
For example:
b = -a
