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:
“When the Devil quotes Scriptures, it’s not, really, to deceive, but simply that the masses are so ignorant of theology that somebody has to teach them the elementary texts before he can seduce them.”
—Paul Goodman (1911–1972)
“Nothing in the world can take the place of Persistence. Talent will not; nothing is more common than unsuccessful men with talent. Genius will not; unrewarded genius is almost a proverb. Education will not; the world is full of educated derelicts. Persistence and Determination alone are omnipotent. The slogan “Press On”, has solved and will always solve the problems of the human race.”
—Calvin Coolidge (1872–1933)
