Use in Elementary Education
Some elementary teachers use raised plus and minus signs before numbers to show they are positive or negative numbers. For example subtracting −5 from 3 might be read as positive three take away negative 5 and be shown as
- 3 − −5 becomes 3 + 5 = 8,
or even as
- +3 − −5 becomes +3 + +5 which is +8

Famous quotes containing the words elementary and/or education:
“Listen. We converse as we live—by repeating, by combining and recombining a few elements over and over again just as nature does when of elementary particles it builds a world.”
—William Gass (b. 1924)
“It’s fairly obvious that American education is a cultural flop. Americans are not a well-educated people culturally, and their vocational education often has to be learned all over again after they leave school and college. On the other hand, they have open quick minds and if their education has little sharp positive value, it has not the stultifying effects of a more rigid training.”
—Raymond Chandler (1888–1959)
