CHRISTMAS ORDER DEADLINES - if you're hoping to receive your order before Christmas, here's the info you need.
In the world of numbers, 220 and 284 are special because they come as a pair. They are a pair because, if you take all the numbers that divide 220 (1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110 – but not 220 itself) and add them together you get 284. However, if you take all the numbers that divide 284 (1, 2, 4, 71, 142 – but not 284 itself) and add them together, you get 220. These are called Amicable Numbers, and in ancient times these numbers represented mutual harmony, perfect friendship and love.
The heart parts of the keyrings are 50mm tall, 3mm thick and fit together like a jigsaw puzzle.
The pack comes with two information sheets about the history and maths of Amicable Numbers. One for you and one for your loved one.
