If S stands for $+$, Z stands for $-$, Q stands for $\times$, M stands for $\div$, then what is the value of the given equation?
66 S 267 M 3 Q 17 Z 89 = ?
1485
1490
1513
1505
Solution
S $\Rightarrow +$ ; M $\Rightarrow \div$ ; Q $\Rightarrow \times$ ; Z $\Rightarrow -$
66 S 267 M 3 Q 17 Z 89
= 66 $+$ 267 $\div$ 3 $\times$ 17 $-$ 89
= 66 $+$ 89 $\times$ 17 $-$ 89
= 66 $+$ 1513 $-$ 89
= 1579 $-$ 89
= 1490
