If '@' stands for '-', '*' stands for 'x', '%' stands for '+', '~' stands for '÷', then find the value of: 8 @ 4 ~ 2 ~ 6 = ?
Show answer & explanation
Correct answer: A
Explanation
Substituting real signs:
'@' = '−', '~' = '÷'
8 @ 4 ~ 2 ~ 6
= 8 − 4 ÷ 2 ÷ 6
Solving division first (left to right):
4 ÷ 2 = 2
2 ÷ 6 = 1/3
Now:
8 − 1/3 = 24/3 − 1/3 = 23/3
