I need to create a formula where the user would start with x and do at least 4 steps (multiplication, division or subtraction... no *0 allowed) to that number and always get 28. For example x = any number x+5 = n 2n+10 = y 2y+ 6 = z final step z+3 = 28 obviously that is nor correct. Thank you!

x = any number Subtract the number from itself and then add 1: x  x + 1 = 1 = n Multiply the result by 2 and then add 10: 2n + 10 = 2(1) + 10 = 12 = y Subtract 2 from the result: y  (2) = 12 + 2 = 14 = z Multiply the result by 2: 2z = 2(14) = 28
