What are the four-steps that should be used in evaluating expressions? Can these steps be skipped or rearranged? Explain your answers with examples.

In evaluating expressions and obtaining a correct answer, a person must follow the following four steps: (1) Evaluate the information in grouping symbols. (2) evaluate anything with an exponent. (3) Multiply and divide in order from left to right (4) Add and subtract in the same order from left to right.

The four steps that should be used in evaluating expressions are as follows:

1. The first step involves the evaluating the information's in grouping symbols.

2. The second step involves evaluating anything that has an exponent.

3. The third step involves multiplying and dividing in an order of left to right.

4. The final and the fourth step involves adding and subtracting in a similar order as the third step.
