Video Summary

Carolyn is forming the number 2022 using matches. The box initially held 30 matches. She's already formed "20", using five matches for the '2' and six matches for the '0'. She will need two more '2's, each requiring five matches. Calculating the total, 5 (first '2') + 6 ('0') + 5 (second '2') + 5 (third '2') amounts to 21 matches. Subtracting this from the original 30 matches, Carolyn will have 9 matches remaining once she's finished forming the number 2022.
