PACKET #7 Introduction to Mathematics

Definition Mathematics  A science of structure and order  Evolved from counting measuring and describing the shapes of objects  Deals with logical reasoning and quantitative calculation  Quantitative Relating to number or quantity

Brief History of Mathematics In Africa, a cave was found containing rocks with geometric patterns scratched into it Artifacts discovered in Africa and France dating back to the earliest times on the planet suggest people tried to quantify time. Evidence suggest that women devised counting to keep track of their menstrual cycles

Brief History of Mathematics II In India, the earliest mathematics is dated around 3000 B.C. in the Indus Valley Civilization  Decimal system  Weights  Right angles  Geometric shapes In China  Earliest extant mathematics dates during the Shang dynasty around 1600 B.C. Babylon (modern day Iraq) Egypt Greeks  All had B.C. timelines in regards to mathematics

Today… Mathematics is a science…that is used within science.
