Introduction

In mathematics, the associative property is a fundamental concept that helps us simplify complex calculations by rearranging the order of operations. It is a crucial tool for solving equations and expressions involving multiple operations. In this article, we will explore the associative property in detail, focusing on how to apply it to calculate -12×[11(-23)].

What is the Associative Property?

The associative property is a mathematical concept that states that the order in which we perform operations does not change the result. In other words, when we have multiple operations to perform, we can rearrange them in any order and still get the same result. This property is denoted by the following equation:

(a × b) × c = a × (b × c)

Associative Property in Multiplication

The associative property is particularly useful in multiplication. When we have multiple numbers to multiply, we can rearrange them in any order and still get the same result. For example:

(2 × 3) × 4 = 2 × (3 × 4)

Using the associative property, we can simplify this expression as follows:

(2 × 3) × 4 = 6 × 4 = 24

2 × (3 × 4) = 2 × 12 = 24

As we can see, the order in which we perform the operations does not change the result.

Applying the Associative Property to -12×[11(-23)]

Now that we have a good understanding of the associative property, let's apply it to the given expression: -12×[11(-23)]. To simplify this expression, we need to follow the order of operations (PEMDAS):

Evaluate the expression inside the brackets: -23
Multiply 11 by the result: 11(-23) = -253
