Explanation:
Let’s break it down. The symbols don’t mean what they always do:
- × means +
- ÷ means -
- + means ×
- - means ÷
Here’s your expression:
182 - 13 × 5 + 16 ÷ 44
Let’s substitute each symbol for what it actually means:
- 182 - 13 ? 182 ÷ 13
- 13 × 5 ? 13 + 5
- 5 + 16 ? 5 × 16
- 16 ÷ 44 ? 16 - 44
But pay attention to order. The original order is:
182 - 13 × 5 + 16 ÷ 44
Replace all symbols:
= 182 ÷ 13 + 5 × 16 - 44
Now, the real meaning of expression:
First, handle multiplication and division:
1. 182 ÷ 13 = 14
2. 5 × 16 = 80
So plug in those results:
= 14 + 80 - 44
Now, work left to right:
14 + 80 = 94
94 - 44 = 50
Let’s check the options:
Option 1: 50
Option 2: 62
Option 3: 86
Option 4: 48
So, the answer is Option 1: 50.
- All statements and each change in symbol matter for the final result.
- The real calculation is 182 ÷ 13 + 5 × 16 - 44.
- Always follow the real meaning, not the visible symbols.
- You got it. Option 1 is correct, and it’s plugged in cleanly.
