- subtraction and unary minus, e.g., if x=3 and y=2, x-y produces 1 and -x produces -3
^ exponentiation (a^b means ab), e.g., if x=3 and y=2, x^y produces 9
* multiplication, e.g., if x=3 and y=2, x*y produces 6
/ division, e.g., if x=3 and y=2, x/y produces 1.5
> greater than, e.g., if x=3 and y=2, x>y produces 1
< smaller than, e.g., if x=3 and y=2, x<y produces 0
>= greater or equal than, e.g., if x=3 and y=2, x>=y produces 1
<= smaller or equal than, e.g., if x=3 and y=2, x<=y produces 0
<> not equal, e.g., if x=3 and y=2, x<>y produces 1
= equal, e.g., if x=3 and y=2, x=y produces 0
? : ternary conditional operator like in C, C++ or Java programming languages.
This operator is essentially a shortcut to the If function. For example, a=b?5:3 is equivalent to If(a=b, 5, 3).

To change the order of calculation, enclose in parentheses those parts of the formula that should be calculated first. This can be done recursively, i.e., parentheses can be nested indefinitely. For example, if x=3 and y=2, 2*y+x/3-y+1 produces 4, 2*(y+x)/(3-y)+1 produces 11, and 2*((y+x)/(3-y)+1) produces 12.
