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:
“If men as individuals surrender to the call of their elementary instincts, avoiding pain and seeking satisfaction only for their own selves, the result for them all taken together must be a state of insecurity, of fear, and of promiscuous misery.”
—Albert Einstein (1879–1955)
“Quintilian [educational writer in Rome around A.D. 100] thought that the earliest years of the child’s life were crucial. Education should start earlier than age seven, within the family. It should not be so hard as to give the child an aversion to learning. Rather, these early lessons would take the form of play—that embryonic notion of kindergarten.”
—C. John Sommerville (20th century)
