## Operator-precedence parser – Wikipedia

en.wikipedia.orgIn computer science, an operator **precedence** parser is a bottom-up parser that interprets an operator-**precedence** grammar.For example, most calculators use operator **precedence** parsers to convert from the human-readable infix notation relying on order of **operations** to a format that is optimized for evaluation such as Reverse Polish notation (RPN).

## How to Use Operator Precedence in Algebra

intmath.comOperator **Precedence** AKA Order of **Operations**. There are situations in algebra when more than one operator is used in an expression. We must now determine which operation to do first. Here is an example of this instance: x + y * 6. Let’s now assume x = 2 and y = 3. Your possible solutions could be:

## Python Operators Precedence Example – Tutorialspoint

tutorialspoint.comOperator **precedence** affects how an expression is evaluated. For example, x = 7 + 3 * 2; here, x is assigned 13, not 20 because operator * has higher **precedence** than +, so it first multiplies 3*2 and then adds into 7. Here, operators with the highest **precedence** appear at the top of the table, those with the lowest appear at the bottom. Example

## The Order of Operations: PEMDAS | Purplemath

purplemath.comTo eliminate this confusion, we have some rules of **precedence**, established at least as far back as the 1500s, called the "order of **operations**". The "**operations**" are addition, subtraction, multiplication, division, exponentiation, and grouping; the "order" of these **operations** states which **operations** take **precedence** (are taken care of) before which other **operations**.

## bitmap – Bitwise operators order of precedence – Stack …

stackoverflow.comThe order of **operations** will depend on the language. I plugged c AND a OR b into Wolfram Alpha and it gives me (c AND a) OR b. Also c OR a AND b gives me c OR (a AND b) so it does look like in Wolfram Alpha AND has higher **precedence** than OR. These are logical operators instead of bitwise, but I think they’d follow the same pattern.

php.netOperator **precedence** and associativity only determine how expressions are grouped, they do not specify an order of evaluation. PHP does not (in the general case) specify in which order an expression is evaluated and code that assumes a specific order of evaluation should be avoided, because the behavior can change between versions of PHP or depending on the surrounding code.
