## Associative Property

### (a+b)+c=a+(b+c)

The associative property is a fundamental property of arithmetic and algebra, which states that the way we group the terms in an expression does not affect the result of an operation.

In other words, for any three operands a, b, and c, the associative property says that:

(a + b) + c = a + (b + c)

and

(a x b) x c = a x (b x c)

This property applies to the arithmetic operations of addition and multiplication, as well as to other mathematical operations such as composition of functions, union and intersection of sets, and matrix multiplication.

The associative property allows us to group terms in an expression or equation in any way we like, without changing its meaning or solution. For example, in the equation 2 + 3 + 4 = 9, we can group the terms on the left-hand side using the associative property as (2 + 3) + 4 = 5 + 4 = 9, or as 2 + (3 + 4) = 2 + 7 = 9. This shows that the equation is true for all values of the operands, and illustrates the power of the associative property in simplifying algebraic expressions.

It is important to note that not all mathematical operations are associative. For example, subtraction and division are not associative, since (a – b) – c is not equal to a – (b – c), and (a / b) / c is not equal to a / (b / c) in general. The associative property is a key property in many branches of mathematics and plays a crucial role in the development of mathematical theories and applications.
