Salix is a black rabbit who lives in Nottingham with Sarah and Brendan. Unusually for a rabbit, Salix is very numerate and likes to give demonstrations of her mathematical ability. Today she has linked up with her friends Susy and Sal to make a 'Rabbit Calculator'
To use the calculator select each of the two top rabbits in turn by clicking on it, and change its position with the hop left and hop right buttons. Clicking on the add or multiply buttons will then set the position of the third rabbit to be either the sum or product of the first two.
