Penjumlahanandifference

Penjumlahanandifference is a term encountered in informal contexts to refer to the pair of arithmetic operations addition and difference (subtraction). It is not a formal concept with a single definition across mathematics, but rather a descriptor used to discuss both operations, their properties, and their interrelation.

Penjumlahan refers to the addition operation. For numbers, a + b equals the sum. Addition is associative

Difference commonly means subtraction: a - b. Subtraction is not commutative: a - b ≠ b - a in general.

Because addition and subtraction are inverse operations, they are closely linked, and many problems can be

Common related topics include addition, subtraction, absolute value, and arithmetic properties.
