Number conundrums

1)

Each of the three big circles passes through four small white circles. Place the digits from 1 to 6 in the white circles so that the numbers on each big circle add up to 14.

2)

Place the digits from 1 to 8 in the circles such that no number is connected by a line to a number either 1 more or 1 less than itself. For instance, 6 cannot be connected to 5 or 7.

3)

Divide this clock face with two straight lines so that the sum of the numbers in each section is the same.

4) Place the digits indicated in the squares so that each equation makes sense. For example, the first one uses the digits 1,2,3 and 4.

5)

Place seven digits from 1 to 9 in the circles so that the three digits on each line multiply to the same amount.

6)

In the triangle the digits from 1 to 6 are positioned such that the difference between two adjacent numbers is shown in the row beneath them.

Do the same for the digits 1-10 in the triangle on the left, and the digits 1-15 in the triangle on the right.
