Formulas

Expressions can be combined using operators. Each operator as a precedence priority. Here is the list of those expression’s priority.

1. primary
2. unary
3. multiplicative
4. additive
5. relational
6. logical

Logical

These operators can do some logical comparison between other expressions: or, || and, &&

  true or false and true

The and operator has more priority thand the or, thus in the example above, false and true is evaluated first.

Relational

=, ==, !=, <> <, <=, >, >=

  1 < 2

Additive

+, –

  1 + 2 - 3

Multiplicative

*, /, %

 1 * 2 % 3

Bitwise

& (bitwise and), | (bitwise or), ^(bitwise xor), << (left shift), >>(right shift)

  2 >> 3

Unary

!, not, -, ~ (bitwise not)

  not true

Primary

(, ) values

  2 * ( 3 + 2 )
