In this type of questions, question is provided with substitutes for various mathematical symbols, followed by a question involving calculation of an expression or choosing the correct/incorrect equation. You have to put the real signs in the given equation and then solve the questions as required.
If '&' stands for '+', '^' stands for '-', '!' stands for '÷', '~' stands for '×', then find the value of: 6 ^ 8 ^ 7 ! 5 = ?
Show answer & explanation

! = ÷
˜ = ×
6 ^ 8 ^ 7 ! 5
Now let's replace the symbols with the actual symbols:
6-8−7÷5=?
6-8−7/5=?
? = 6-47/5
? = -17/5
