Recorde's Whetstone of Witte

The whetstone for exercise

Whetstone of Witte is one of the earliest English texts on algebra. Robert Recorde (1510–1558) opened this work with a poem, then proceeded to discuss such fundamental algebraic topics as the subtraction of polynomials, notation for an unknown variable and use of the quadratic equation in problem solving.
