In solution they simply say A =120 without giving solution and further calculate value of Y

|6|2|3|  +
|6|5|  -             (2+3=5)
|1|                   (6-5=1)
|1|3|8|2| /
|1|3|4|+          (8/2=4)
|1|7|*             (3+4=7)
|7|                 (1*7=7)

|7|3|^           (7^3 = 343)
|343|3|+
|346|

Therefore A=346

Y= 2*346+16 = 708
