Each box contains 3 apples and 4 pears. Applying a bit of maths terminology we could write this as (3 apples + 4 pears ) with the brackets showing that they are boxed together.

There are 5 boxes in the gift box or 5 × (3 apples + 4 pears )

There is a total of 5 × 3 apples and 5 × 4 pears or

5 × (3 apples + 4 pears ) = 5 × 3 apples + 5 × 4 pears = 15apples + 20pears.

Now instead of replacing the apples and pears with known numbers use

*s and*

**x****s.**

*y*In maths this is 5×(3

*+ 4*

**x***) or 5(3*

**y***+ 4*

**x****)**

*y*In total there 5×3

*s and 5×4*

**x***s*

**y**or 5(3

**+ 4**

*x***)=5×3**

*y**+ 5×4*

**x****=15**

*y**+ 20*

**x**

*y*In the Game of Maths we use holders rather than boxes.

In cards the following hands give the same result whatever numbers are declared for

**and**

*x***.**

*y*5(3

*+ 4*

**x****)**

*y*5×3

*+ 5×4*

**x**

*y*Wherever there is a gap (or a change of card) above the long holder cut it into card sized holders
