In mathematics, equivalent expressions are those that have the same value or result when evaluated. This concept is crucial in algebra and other branches of mathematics, as it allows us to simplify complex expressions and solve equations. In this article, we will explore the concept of equivalent expressions and examine which of the given options are equivalent to the expression ${-1(0)=0}$ .

What are Equivalent Expressions?

Equivalent expressions are expressions that have the same value or result when evaluated. For example, the expressions ${2+2}$ and ${4}$ are equivalent because they both equal 4. Similarly, the expressions ${3\times 5}$ and ${15}$ are equivalent because they both equal 15.

Evaluating the Given Options

Now, let's evaluate each of the given options to determine which ones are equivalent to the expression ${-1(0)=0}$ .

Option A: ${-1[4+(-4)]}$

To evaluate this expression, we need to follow the order of operations (PEMDAS):

Evaluate the expression inside the brackets: ${4+(-4)=-4}$
Multiply the result by -1: ${-1(-4)=4}$

Therefore, option A is equivalent to the expression ${4}$ , not ${0}$ .

Option B: ${-1[4+(4)]}$

To evaluate this expression, we need to follow the order of operations (PEMDAS):

Evaluate the expression inside the brackets: ${4+(4)=8}$
Multiply the result by -1: ${-1(8)=-8}$

Therefore, option B is not equivalent to the expression ${0}$ .

Option C: ${1+[4+(-4)]}$

To evaluate this expression, we need to follow the order of operations (PEMDAS):

Evaluate the expression inside the brackets: ${4+(-4)=0}$
Add 1 to the result: ${1+0=1}$

Therefore, option C is not equivalent to the expression ${0}$ .

Option D: ${-1[-4+(-4)]}$

To evaluate this expression, we need to follow the order of operations (PEMDAS):

Evaluate the expression inside the brackets: ${-4+(-4)=-8}$
Multiply the result by -1: ${-1(-8)=8}$

Therefore, option D is not equivalent to the expression ${0}$ .

Conclusion

In conclusion, none of the given options are equivalent to the expression ${-1(0)=0}$ . The correct answer is not among the options provided. However, we can see that option A is equivalent to the expression ${4}$ , which is a different value.

Why is this Important?

Understanding equivalent expressions is crucial in mathematics because it allows us to simplify complex expressions and solve equations. By recognizing equivalent expressions, we can rewrite equations in different forms, making it easier to solve them.

Real-World Applications

Equivalent expressions have many real-world applications. For example, in physics, equivalent expressions can be used to describe the motion of objects. In economics, equivalent expressions can be used to model the behavior of markets.

Tips and Tricks

When working with equivalent expressions, it's essential to follow the order of operations (PEMDAS). This will ensure that you evaluate the expressions correctly and avoid errors.

Common Mistakes

One common mistake when working with equivalent expressions is to forget to follow the order of operations (PEMDAS). This can lead to incorrect results and errors.

Conclusion

In conclusion, equivalent expressions are a fundamental concept in mathematics that allows us to simplify complex expressions and solve equations. By understanding equivalent expressions, we can recognize different forms of equations and solve them more efficiently. In this article, we evaluated four options to determine which ones are equivalent to the expression ${-1(0)=0}$ . Unfortunately, none of the options were equivalent, but we learned some valuable lessons about equivalent expressions and their importance in mathematics.

Final Thoughts

Equivalent expressions are a powerful tool in mathematics that can help us solve complex problems. By understanding equivalent expressions, we can recognize different forms of equations and solve them more efficiently. In the next article, we will explore more advanced concepts in mathematics and their real-world applications.
