8−2⋅3+7

Answer 1

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 \(9\).
