Explanation:

Let’s break down the symbol switch first:

- “÷” actually means “-”

- “-” actually means “×”

- “×” actually means “+”

- “+” actually means “÷”

So, rewrite the expression with real math symbols:

- 132 + 6 - 9 × 13 ÷ 31

becomes

- 132 ÷ 6 × 9 + 13 - 31

Now, go step by step using the real meanings:

- 132 ÷ 6 = 22

- 22 × 9 = 198

- 198 + 13 = 211

- 211 - 31 = 180

Here’s what you get with each option:

- Option 1: 180

- Option 2: 206

- Option 3: 216

- Option 4: 208

So, the answer is 180.

Quick recap:

- The question wanted you to swap all the symbols before solving

- Plug in the switched symbols and calculate step by step

- Double-check the order, do operations as you would with normal rules

- Option 1, 180, is exactly correct

That’s how you nail these problems.
