Let the number of stickers that Bryan has be 1 u.
Charlie has 20 stickers less than Bryan.
Charlie has 10 stickers less than Adam.
Number of stickers that Charlie has = 1 u - 20

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

Total number of stickers
= 1 u - 20 + 1 u - 10 + 1 u
= 1 u + 1 u + 1 u - 20 - 10
= 3 u - 30
