Once upon a time battery powered and smart phone enabled calculators didn’t exist. How on earth did people figure out multiplication figures? Turns out in 1916 all you needed were monkeys! Based on Consul the Educated Monkey which was invented in 1916 by William Robertson these teaching aids were a hit with kids learning their multiplication tables.
It’s simple to use and all mechanical. To find out the right answer for any 12×12 multiplication sum all you will need to slide the feet to the required number and the answer will be revealed in his hands!
These replica Tin Educated Monkey Calculator’s comes fitted with a handy stand and is a great novelty gift for those who love to indulge in a bit of history.
