Solution 1
Seven: "Sum of 7" = 4 + 2 + 1 (4, 2, and 1 are powers of 2)
Twelve: "Sum of 12" = 8 + 4 (8 and 4 are powers of 2)
Fifteen: "Sum of 15" = 8 + 4 + 2 + 1 (8, 4, 2, and 1 are powers of 2)
Thirty-Three: "Sum of 33" = 32 + 1 (32 and 1 are powers of 2)
Solution 2
Seven: "Sum of 7" = 4 + 2 + 1 (powers of two: 2^2 + 2^1 + 2^0)
