To solve the expression \(8 - 2 \cdot 3 + 7\), we should follow the order of operations (PEMDAS/BODMAS):
1. **Multiplication**: Calculate \(2 \cdot 3\).
\[
2 \cdot 3 = 6
\]
The expression now becomes:
\[
8 - 6 + 7
\]
2. **Subtraction and Addition**: We perform the operations from left to right. First, do the subtraction:
\[
8 - 6 = 2
\]
Now the expression is:
\[
2 + 7
\]
3. Finally, do the addition:
\[
2 + 7 = 9
\]
Therefore, the value of the expression \(8 - 2 \cdot 3 + 7\) is \(9\).
