If ‘–’ stands for ‘÷’, ‘+’ stands for ‘×’, ‘÷’ stands for ‘–’ and ‘×’ stands for ‘+’, then what is the value of the following expression?
$$80-20+10÷8\times 10$$

According to the question, we substitute the signs as follows:$-$ becomes $÷$$+$ becomes $\times$$÷$ becomes $-$$\times$ becomes $+$ Substituting these into the given expression:
$$80÷20\times 10-8+10$$
Now, apply the BODMAS rule:Division:
$$80÷20=4$$
The expression becomes: $4\times 10-8+10$ Multiplication:
$$4\times 10=40$$
The expression becomes: $40-8+10$ Addition and Subtraction:
$$40+10-8=50-8=42$$
Hence, the correct value is 42.
