i tried to do following.. 2$3=8 8+5=13 13*2=26 26$2=776 776-6=770 770/6=128.33 but as per this, this is infix express evaluation but given question is to evaluate postfix expression..

I think, that first numbers will be multiplied and divided, and then added and subtracted. if you do not use brackets in the expression. by default, operators will be prioritized

The only language I know that uses the dollar operator is Haskell and in Haskell it basically means “evaluate the right side first” If it’s exponentiation, though, then you messed up the order of operations. It would be (2**3) + 5(2**2) - (6/6) 8 + 5(4) - 1 8 + 20 - 1 28 - 1 27
