You have added the 5 twice, haven't you ? You have followed bodmas so it should be
One shoe on man 5
Second shoe on man 5
one paper 2
second paper 2
total : 14
multiplied by
one paper 2
equals 28
plus
shoe on own 5
= 33
You can't add the shoe on the left to the first set of calculations and then add it in again at the end
