He held the position of Professor of Mathematics at Woolwich Military Academy for thirty-four years and wrote numerous mathematics textbooks. In 1781 Hutton published "Mathematical Tables for the Board of Longitude and he later produced the important "Course of Mathematics (1798-1801), which was subsequently published in various editons over a period of fifty years.
