To figure out a special number, Tammi’s mother was supposed to double her age and then add 4. Instead, Tammi’s mother added 4 to her age and then doubled that number. Tammi’s mother thought the special number was 80. What was the special number supposed to be?

Explanation:

36 plus 4 x 2 = 80 what her mom got but it’s 76 because 36x2 is 72 and 72 plus 4 is 76.
