To simplify the expression \( 12 - 23 + 4 \div 2 + 24 \), we will use the order of operations (PEMDAS/BODMAS).
-
Division first: \[ 4 \div 2 = 2 \]
-
Now substitute back into the expression: \[ 12 - 23 + 2 + 24 \]
-
Perform the operations from left to right:
- Start with \( 12 - 23 \): \[ 12 - 23 = -11 \]
- Now add \( 2 \): \[ -11 + 2 = -9 \]
- Now add \( 24 \): \[ -9 + 24 = 15 \]
So, the simplified result is \( 15 \).
