Ready Reckoner??

Does anyone know what a ready reckoner is and what its purpose is?? Mathematically speaking. It asks me a question about this on my work sheet, but nowhere in the textbook nor in the booklets, does it state what the hell this thing is.

Thanx

A quick Google search shows that a "ready reckoner" is a general expression or either a calculator or a table. Kind of like those little business cards with tables to show you how much to tip on the back. Or the financial apps that tell you how much your monthly payment will be for each $1,000 borrowed at various interest rates. Those are ready reckoners.
