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 1600s

William Ougthered invent Slide Rule in 1622!
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.
William Oughtred and others developed the slide rule in the 17th century based on the emerging work on logarithms by John Napier.
Before the invention of the pocket or handheld calculator, the slide rule was a popular tool for calculations. William Oughtred made the first slide rule by inscribing logarithms on wood or ivory. The use of slide rules continued until about 1974, after which electronic calculators became more popular.

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.
Oughtred's slide rule, invented by the English mathematician William Oughtred in the early 17th century, was first introduced in 1622. It is a mechanical calculating device that uses a linear scale to perform multiplication and division, making calculations more efficient. Oughtred’s design laid the groundwork for modern slide rules, which became essential tools for engineers and scientists until the advent of electronic calculators.
