Within a single expression, opertions with larger precedence numbers (as shown below) are perfomed below those with smaller numbers; operations at the same level are performed in order of association.
Style tip: when writing expressions that use operators having different precedence levels, the use of parentheses is encouraged. Even if they are, technically, not needed, their use makes the code clearer and less prone to subtle errors (in syntax, semantics, or logic).
