Study Notes

Circulatory System

  • Responsible for pumping blood throughout the body.
  • Transports oxygen, nutrients, hormones, and waste products.

Main Focus

  • Primarily discusses various biological and mathematical systems and their functions.

Skeletal System

  • Provides structure and support to the body.
  • Protects vital organs and enables movement by serving as attachment points for muscles.

Mathematical Operations

  • Addition: Combining two or more numbers to get a total.
  • Subtraction: Taking one number away from another.
  • Multiplication: Repeated addition of a number for a specified number of times.
  • Division: Splitting a number into equal parts or groups.

Geometric Shapes

  • Triangle: A three-sided polygon with angles that sum up to 180 degrees.
  • Rectangle: A four-sided polygon with opposite sides equal and angles at 90 degrees.
  • Circle: A round shape with all points equidistant from the center.
  • Square: A special type of rectangle where all four sides are equal in length.

Algebraic Terms

  • Variable: A symbol representing a number that can change.
  • Constant: A fixed value that does not change.
  • Coefficient: A numerical factor in front of a variable in an algebraic expression.
