700 -10 $÷\frac{1}{2}\times$ 35 + 70 be zero?

• A. $\times$ means $÷$ , + means $\times$, $÷$ means +. - means -
• B. $\times$ means $÷$, + means -, + means $\times$, -means +
• C. $\times$ means +, + means -, $÷$ means $\times$, - means $÷$
• D. $\times$ means $÷$, + means -. + means $\times$ , - means +

Answer 1

Answer: (C)

$\times$ means +, + means -, $÷$ means $\times$, - means $÷$

If it is Option A,
Equation becomes
$700-10+\frac{1}{2}÷35\times 70$
$700-10+1$
691 is not equal to 0
With option C, Equation becomes
$700÷10\times \frac{1}{2}+35-70$
$70\times \frac{1}{2}-35$
$35-35$
$0$
Answer is Option C
