**The Company**

Polymath Limited is a start-up company (March, 2014) based in Wexford , Ireland. It is run by retired maths teacher, Brigid Mc Bride.

Her idea for the all-in-one maths instrument occurred to her while she was still teaching but she didn’t follow up on it until after she had retired.

The ‘ polyMath’ is manufactured in Waterford by Hasbro, now Cartamundi.

**How the idea for the polyMath came about**

One day in class a student was taking a long time to draw a set of parallel lines when making a table for a graph. There was no need to be so particular but that was her nature.

Some time later, out of school and in bed with a bout of ‘flu, this student crossed my mind and I thought that it was a pity that there wasn’t a stencil which would enable her to draw a set of evenly-spaced parallel lines quickly . It was obvious that the shape of this stencil would have to be a rectangular frame with cross bars. Then I wondered if anything else could be added. I could see immediately that a ruler could be on one of the outside edges and that a 180 degree protractor could be on the other three sides. I could also see that, with the aid of another straight edge, it could be used to draw a line parallel to a given line through a given point – as is usually done using two protractors.

It occurred to me that if it could be used as a compass it would be an all-in-one geometry set. I couldn’t see how that would be possible and put it out of my mind. About ten minutes later , a eureka moment! Put in tiny holes and to draw a circle you would hold the instrument in position with a pencil in one hole and rotate it with another pencil in a second hole. Problem solved!

**The instrument**

With the **polyMath**

- You can draw circles – it’s a
**compass.**

Radii of circles you can draw

From 1 cm to 8 cm in 1 mm intervals

Also 0.5 cm 8.5 cm 9.0 cm 9.5 cm 10.0 cm

If you need to draw a circle, given its centre and a point on the circle, use a ‘**slide**’. - You can draw and measure line segments – it’s a
**10 cm ruler** - You can draw a line parallel to a given line (with the help of any other straight edge) – as with two
**setsquares** - You can draw and measure angles – it’s a 180°
**protractor** - You can draw a set of parallel lines – it’s a
**parallel line stencil** - It may also be useful as a reading aid.
