4+484:242•249-995

To solve the expression \(4 + \frac{484}{242} \cdot 249 - 995\), we will follow the order of operations (PEMDAS/BODMAS):

1. Calculate \( \frac{484}{242} \): \[ \frac{484}{242} = 2 \]

2. Substitute this back into the expression: \[ 4 + 2 \cdot 249 - 995 \]

3. Perform the multiplication: \[ 2 \cdot 249 = 498 \]

4. Substitute again: \[ 4 + 498 - 995 \]

5. Add \(4 + 498\): \[ 502 - 995 \]

6. Finally, subtract \(995\) from \(502\): \[ 502 - 995 = -493 \]

So, the final result is: \[ \boxed{-493} \]
