Division 1
The word ‘divide’ was used in mathematics from the early 15th century. It comes from the Latin, dividere meaning ‘to force apart, cleave or distribute’. Interestingly, the word widow has the same etymological root, which can be understood in the sense that a widow is a woman forced apart from her husband.

The division symbol ÷ is known as the obelus. It was first used to signify division in 1659. We read the statement 12 ÷ 3 as ‘12 divided by 3’. Another way to write division in school arithmetic is to use the notation , meaning ‘12 divided by 3’, but sometimes read as
‘3 goes into 12’. Mathematicians almost never use the ÷ symbol for division. Instead they use fraction notation. The writing of a fraction is really another way to write division. So 12 ÷ 4 is equivalent to writing , where the numerator, 12, is the dividend and the denominator, 4, is the divisor. The line is called called a vinculum, which is a Latin word meaning ‘bond or link’. |
