The Mathemagician needs to break a dreadful spell! Help him to find the magic number that will do the trick!

Here is the hepta-tree hung with silver balls.

Do you think the balls will have similar values?

Try estimating the amount on each ball.

In order to break the spell, firstly find the exact difference between the largest ball and the smallest ball.

Multiply your result by $244$.

Round this to a whole number and that gives us the MAGIC NUMBER!

Give this number to the Mathemagician and the terrible spell will be broken for ever!

Place this "worm" on the 100 square and find the total of the four squares it covers. Keeping its head in the same place, what other totals can you make?

There are six numbers written in five different scripts. Can you sort out which is which?

Put operations signs between the numbers 3 4 5 6 to make the highest possible number and lowest possible number.
