Puzzle triangles

Six discs are joined by one-way arrows and two-way links, as shown in our picture. Each arrow means you add 4 to the number the arrow begins on and then divide the result by 6 and keep the remainder and put that in the disc the arrow points to. The puzzle is to give each disc its num ber, from 0 up to 6. For example, you begin at 0, already marked. Add 4 and the result is 4; divide by 6 and keep the remainder, 4, and put that in the disc the arrow points to. Also, on the inner triangle, beginning on 3 (already
marked), the disc pointed to is 1 because (3 + 4)/6 leaves a remainder of 1. The difference between the numbers on the discs at either end of each two-way link is 3. See if you can fill in all the discs.
