The slide rule was invented during the period of 1620-1650 by William Oughtred, based on the earlier invention of the Gunter scale by Edmund Gunter. The original slide rule is said to have been circular, and come about 1620 or 1625. The straight slide rule is said to have been invented around 1650.

The slide rule was invented by William Oughtred in about 1620.

AnswerThe slide rule was invented by William Oughtred in 1625. AnswerWe do not know the precise year. A circular slide rule was invented by William Oughtred some time about 1620, and a design of a similar slide rule by Delamain was printed in about 1630. The straight slide rule seems to have been invented later, some time around 1650.

The slide rule was invented by William Oughtred some time about 1620 or 1625.

The slide rule was invented in England, by William Oughtred, in about 1620. This probably happened in Albury, near Guildford, in Surrey, where he lived. Records are not specific.

a person invented it. i do abid you a good day now.

William Oughtred and others developed the slide rule in the 17th century based on the emerging work on logarithms by John Napier.

Well.. the purpose of the slide rule is that, to count, add, subtract, multiply, and divide. For as its structure is like a ruler and has a transparent slider. It is the type of a cursor, used for pointing out the numerals/ numbers. It is the third calculator invented, after Napier's bones. It was invented by Napier, as well.

The slide rule very much simplified calculations of multiplication and division, especially were a ratio was to be used over and over. Edmund Gunter had already invented the Gunter scale, but it was clumsy and required dividers (the things like compasses, but with two sharp ends instead of one sharp end and a piece of pencil lead) to use. William Oughtred realized that two Gunter scales facing each other made it unnecessary to use the dividers. That realization was the invention of the slide rule. The slide rule was developed to perform multiplication and division before calculators had been invented. a addition and subtraction

Slide calipers was invented by the French mathematician Pierre Vernier.It was known as Vernier calipers.

The slide rule, also known as a slipstick, is a mechanical analog computer. The slide rule is used primarily for multiplication and division, and also for "scientific" functions such as roots, logarithms and trigonometry, but does not generally perform addition or subtraction. William Oughtred and others developed the slide rule in the 1600sThere are pictures and information about slide rules at the Wikipedia article listed in the related links below.

Slide rules were replaced by pocket calculators. This happened very suddenly as soon as the price of the calculator became comparable with the slide rule. The market for the slide rule dried up almost completely, in much of the world, in less than a year. Some specialty slide rules have survived, however.
