Napier's Bones

  • Invented by John Napier in 1614.
  • Allowed for multiplication, division, and calculating square and cube roots by moving rods on a specially constructed board.

Slide Rule

  • Invented by William Oughtred in 1622.
  • Based on Napier's ideas about logarithms.
  • Used for multiplication, division, roots, logarithms, and trigonometry.
  • Not typically used for addition or subtraction.

Pascaline

  • Invented by Blaise Pascal in 1642.
