The post-increment and post-decrement operators increase (or decrease) the value of their operand by 1, but the value of the expression is the operand's value prior to the increment (or decrement) operation. In languages where increment/decrement is not an expression (e.g., Go), only one version is needed (in the case of Go, post operators only).
Augmented assignment (or compound assignment) is the name given to certain assignment operators in certain programming languages (especially those derived from C).An augmented assignment is generally used to replace a statement where an operator takes a variable as one of its arguments and then assigns the result back to the same variable.
The order of operations, that is, the order in which the operations in an expression are usually performed, results from a convention adopted throughout mathematics, science, technology and many computer programming languages.
The semantics of operators particularly depends on value, evaluation strategy, and argument passing mode (such as Boolean short-circuiting). Simply, an expression involving an operator is evaluated in some way, and the resulting value may be just a value (an r-value), or may be an object allowing assignment (an l-value).

The article states that the "increment operator increases the value of its operand by 1", but this is only sometimes correct, and misses the point of the operator. The operator actually increases the value by an amount that reflects the number of machine words required to store the data.
If [ r1 ] ≤ 0 THEN go to I b else [ r1 ] -1 → r1 and go to I a. Jump to instruction I b if contents of register r1 is zero ELSE decrement (subtract 1 from) contents of register #1 1963: Shepherdson and Sturgis's model
Operators that are in the same cell (there may be several rows of operators listed in a cell) are grouped with the same precedence, in the given direction. An operator's precedence is unaffected by overloading. The syntax of expressions in C and C++ is specified by a phrase structure grammar. [7] The table given here has been inferred from the ...
