Let the number of stickers that Charlie has be 1 u.
Bryan has 30 stickers less than Charlie.
Bryan has 20 stickers less than Adam.
Number of stickers that Bryan has = 1 u - 30

Adam has 20 stickers more than Bryan.
Number of stickers that Adam has
= 1 u - 30 + 20
= 1 u - 10

Total number of stickers
= 1 u - 30 + 1 u - 10 + 1 u
= 1 u + 1 u + 1 u - 30 - 10
= 3 u - 40
