If ‘$$\div$$’ means ‘+’: ‘-’ means ‘$$\times$$: ‘$$\times$$ means ‘$$\div$$’ and ‘+’ means ‘-’: then
$$15-8\times 6 \div 12+4=?$$
Writing down the numbers without the operators between them, we have
15 8 6 12 4
Now inserting the operators with their changed values
15 x 8 $$\div$$ 6 + 12 - 4 = 28, Thus option 2
