**1st and 2nd**

Take ten cards numbered 0 to 9.

1. Pick three cards with a total of 12.

You can do this in 10 different ways. Write down the combination of cards you used.

2. Now pick four cards with a total of 12. How many different ways can you do it?

3. Can you select five cards with a total of 12?

**3rd and 4th**

A

**pandigital**sum (for addition, subtraction, multiplication or division) is one which uses all of the digits 1 to 9 once and once only.

*For example -*

128 + 439 = 567

26 + 48 + 79 = 153

are two pandigital addition sums,

and there are many more like that.

Find

**TWO**other pandigital sums.

**5th and 6th**

A Magic Square is set of numbers arranged in the form of a square so that the total of every

**row, column**and

**diagonal**is the

**same**.

On the right is a Magic Square with 3 rows, 3 columns, and 2 diagonals, so that there are 8 totals to be found, each of which adds up to 15.

An Anti-magic Square has the same arrangement but the total of every row, column and diagonal is

**different**.

Use the same numbers (1, 2, 3, 4, 5, 6, 7, 8 and 9;

**once and only once**) to make an Anti-magic Square with the added restriction that none of the 8 different totals must be less than 10 or greater than 18.
