Final answer:
The plus and minus symbols were first introduced in printed books by Johannes Widmann in 1489, not by the mathematicians Leonardo of Pisa (Fibonacci), Euclid, Archimedes, or Isaac Newton.
Step-by-step explanation:
The symbols for plus and minus were first used in printed books by Johannes Widmann in 1489. Neither Leonardo of Pisa (Fibonacci), Euclid, Archimedes, nor Isaac Newton introduced these symbols. While significant accomplishments in science and mathematics were achieved by Euclid and Archimedes, with Euclid being noted for his work on geometry in his work the Elements and Archimedes remembered for his application of geometry to engineering, they did not create these arithmetic symbols. Johannes Widmann, a German mathematician, introduced them in his book Behende und hübsche Rechenung auf allen Kaufmannschaft.
