54. The task is very difficult-

Not everyone can find:

What does the star,

Bicycle and hedgehog equal?

| BICYCLE | HEDGEHOG | 7 |
| :---: | :---: | :---: |
| + STAR | HEDGEHOG | 4 |
| 6 | BICYCLE HEDGEHOG |  |
| 1 BICYCLE | 0 | STAR |

Decode the rebuses:
54. (HEDGEHOG + HEDGEHOG + BICYCLE + 1) ends with the digit 0. Therefore, (HEDGEHOG + HEDGEHOG + BICYCLE) = 9 (or 19). The equation HEDGEHOG + HEDGEHOG + BICYCLE = 19 is impossible. Therefore, the sum 9 is possible, and from the cases 1+1+7=9, 2+2+5=9, 3+3+3=9, and 4+4+1=9, only 2+2+5=9 fits. As a result, HEDGEHOG = 2, STAR = 3, BICYCLE = 5:
