Notation in which the operator separates its operands. E.g. (a + b) * c. Infix notation requires the use of brackets to specify the order of evaluation, unlike either prefix or postfix notations.

Structure notation where the operator is located between the operands, e.g. (A+B).

a notation in which operators appear between the operands, as in 3 + 5

Notation that involves placing the predicate symbol between its arguments (e.g., Michael TALLER Joshua).

Symbols used in arithmetic problems. You might find plus, minus, division, and parentheses. Each symbol has a different meaning and different mathematical action.

Infix notation is the common arithmetic and logical formula notation, in which operators are written infix-style between the operands they act on (e.g. 2 + 2). It is not as simple to parse by computer as prefix notation ( e.g. + 2 2 ) or postfix notation ( e.g. 2 2 + ), but many programming languages use it to take advantage of its familiarity.
