Glossary

A

• Absolute value

  An absolute value of a number x, written as |x|, is the distance from x to 0 on a real number line.
  See Absolute Value Equation

• Accuracy

  How close a measurement is to an actual value.

• Algebra

  The branch of mathematics involving the rules of operations and relations when working with variables.

B

• Bar graph

  A graph with rectangular bars (plotted either vertically or horizontally) with lengths proportional to the values they represent.
  See Pie Charts & Bar Graphs

• BEDMAS

  The most common acronym for order of operations, meaning Brackets first, then Exponents, Division, Multiplication, Addition, and Subtraction.
  See Order of Operations

• Binomial

  A polynomial with two terms or a sum of two monomials; e.g. 5x + 1.
  See Expanding

C

• Calculus
  The branch of mathematics involving limits, derivatives and integrals.
  See Calculus: Introducing the Concept
• Chain Rule
  A formula for the derivative of the composite of two functions: [f(g(x))] ′ = f ′(g(x))∗g ′(x)
  See Derivative Rules
• Circle
  A geometrical shape that consists of the set of points in a plane that are equidistant from a given point (the centre).
  See Introduction to Circles
• Circumference
  The distance around a circle.
  See Introduction to Circles
• Commutative Property
  A property for some operations (such as addition or multiplication) which states that changing the order of the operands does not change the end result: a+b = b+a.
