Evaluate 10112+1224 ${1011}_2+{122}_4$, leaving your answer in base 10

Answer Details

10112 ${}_2$ = 1 × 23 ${}^3$ + 0 × 22 ${}^2$ + 1 × 21 ${}^1$ + 1 × 20 ${}^0$
1 × 8 + 0 × 4 + 1 × 2 + 1 × 1 = 8 + 0 + 2 + 1 = 11
1224 ${}_4$ = 1 × 42 ${}^2$ + 2 × 41 ${}^1$ + 2 × 40 ${}^0$
1 × 16 + 2 × 4 + 2 × 1 = 16 + 8 + 2 = 26
11 + 26 = 37
