Today's puzzles are about separating digits. [Please don't stick any of the answers in the comments box, and no blatant hints please, but do tell us how you get on]
Look at this row of digits.
There's one digit between the two 1s, there are two digits between the two 2s, and there are three digits between the two 3s.
Got the idea?
Separation puzzle (1) Now try the same thing, but using two 1s, two 2s, two 3s and two 4s. Start by making sure there are four digits between the two 4s.
Separation puzzle (2) Now try the same thing, but using two 0s, two 1s, two 2s, two 3s and two 4s.
Separation puzzle (3) Finally, try the same thing using pairs of 1s, 2s, 3s, 4s, 5s, 6s and 7s.
