Certainly! Let's solve the expression [tex]\(27 - 18 + (-4) - 6\)[/tex] step-by-step.
The expression involves basic arithmetic operations: subtraction and addition. We'll handle these operations following the standard order of operations (from left to right for addition and subtraction).
Step-by-Step Solution:
1. Start with the given expression:
[tex]\[
27 - 18 + (-4) - 6
\][/tex]
2. Perform the first subtraction:
[tex]\[
27 - 18 = 9
\][/tex]
Now, the expression is:
[tex]\[
9 + (-4) - 6
\][/tex]
3. Add [tex]\((+9)\)[/tex] and [tex]\((-4)\)[/tex]:
[tex]\[
9 + (-4) = 5
\][/tex]
Now, the expression is:
[tex]\[
5 - 6
\][/tex]
4. Finally, perform the last subtraction:
[tex]\[
5 - 6 = -1
\][/tex]
So, the result of the expression [tex]\(27 - 18 + (-4) - 6\)[/tex] is [tex]\(-1\)[/tex].
If you wanted to use pandas to evaluate the expression, in a correct manner, you'd need to use python code as follows:
```python
import pandas as pd
# Given expression
expression = "27 - 18 + (-4) - 6"
# Evaluate the expression using pandas
result = pd.eval(expression)
print(result) # This should print: -1
```
