To help you structure your evaluation process, I'll outline the steps you would take according to the order of operations (often remembered by the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).
### Given Expression
Let's say you have an expression that involves the variable \( x \) (for example, an expression like \( 3x + 2(5) - x^2 \)).
### Steps for Evaluating an Expression with x
1. **STEP 1: Substitute the Value of x**
- Replace \( x \) with its given value. For example, if \( x = 2 \), you would replace \( x \) with 2 in the expression.
2. **STEP 2: Evaluate Parentheses**
- If there are parentheses in the expression, evaluate those first. For example, if you have \( 2(5) \), calculate that to get 10.
3. **STEP 3: Evaluate Exponents**
- Evaluate any exponents in the expression. For example, if there is \( x^2 \), compute that based on the substituted value of \( x \).
4. **STEP 4: Perform Multiplication and Division**
- Next, perform any multiplication and division from left to right. For example, if you have \( 3(2) \), compute that multiplication.
5. **STEP 5: Perform Addition and Subtraction**
- Finally, perform any addition and subtraction from left to right to find the final value of the expression.
### Example Filled Out
Here is an example with hypothetical values:
- **Expression:** \( 3x + 2(5) - x^2 \)
- **Value of x:** 2
### Steps Filled Out:
| STEP | 1 | 2 | 3 | 4 | 5 |
|---------------|---------|-----------|------------|----------------|-----------------|
| **Action** | Substitute (3(2) + 2(5) - (2^2)) | Evaluate Parentheses (3(2) + 10 - 4) | Evaluate Exponents (3(2) + 10 - 4) | Perform Multiplication (6 + 10 - 4) | Perform Addition/Subtraction (12) |
| **Result** | 6 | 16 | 16 | 12 | 12 |
### Final Output
- The final result of evaluating the expression for \( x = 2 \) is **12**.
You would fill your table similarly based on the expression you are evaluating and the value of \( x \) that you are using. Adjust your expression and the value of \( x \) as necessary!
