The text at the top of the page uses Stevin's notation, 5(2), for example, for what we would now write as

At the bottom of the page are two references to Stevin's

, pages 289 and 293. On page 289 Stevin deals with equations of the form: square = number – roots. On page 293 he deals with the form: square = roots – number. Stevin's example is 1(2) = 6(1) – 5 (in modern notation
