Mathematical Terms

• Absolute Value - How far a number is from zero.
• Acute Angle - An angle less than 90 (90 is
  called a Right Angle)
• Acute Triangle - A triangle that has all angles
  less than 90 (90 is called a Right Angle)
• Add - To bring two or more numbers (or things)
  together to make a new total.

3
Mathematical Terms

• Addend - Any of the numbers that are added
  together.
• Addition - Is finding the total, or sum, by
  combining two or more numbers.
• Adjacent Angles lying next to each other.
• Algebra - Is the area of mathematics where
  letters (like x or y) or other symbols are used
  to represent unknown numbers.
• Algorithm - Is a step-by-step solution to a
  problem.

Mathematical Terms

• Angle - The amount of turn between two straight
  lines that have a common end point (the vertex).
• Annual - Something that happens once a year.
• Anticlockwise - Moving in the opposite direction
  to the hands on a clock. Also called
  counterclockwise. Angles are usually measured
  anticlockwise.
• Area - The size of a surface. The amount of space
  inside the boundary of a flat (2-dimensional)
  object such as a triangle or circle.

5
Mathematical Terms

• Arithmetic - The basic calculations we make in
  everyday life addition, subtraction,
  multiplication and division. It also includes
  fractions and percentages (related to division)
  and exponents (related to multiplication).
• Array - Items (such as objects, numbers, etc.)
  arranged in rows and columns.
• Ascending Order - Arranged from smallest to
  largest. Increasing.

6
Mathematical Terms

• Asymmetry - Means "no symmetry. Something with
  no symmetry is asymmetrical. It is also possible
  to be symmetrical in one way and asymmetrical in
  another.
• Average - The average is a calculated "central"
  value of a set of numbers. It is easy to
  calculate add up all the numbers and divide by
  how many numbers there are and you will have the
  average. Example the average of 4, 6 and 11 is
  (4611)/3 21/3 7

7
Mathematical Terms

• Axis (geometry) - An imaginary line around which
  something rotates
• Axis (graph) - A reference line drawn on a graph
  (you can measure from it to find values).
• Axis of Symmetry - A line through a shape so that
  each side is a mirror image. If the shape were to
  be folded in half along the axis of symmetry,
  then the two halves would be the same, they would
  match up.

8
Mathematical Terms

• Balance - When both sides have the same quantity
  or mass.
• Balance Scales - A device for weighing. It has a
  balanced beam and two pans. When the pans contain
  exactly the same mass the beam will be in
  balance. You can place an object in one pan and
  standard weights in the other to find what the
  object weighs.
• Bar Graph - A graph drawn using rectangular bars
  to show how large each value is. The bars can be
  horizontal or vertical.

Mathematical Terms

• Base (geometry) - The lowest part. The surface
  that a solid object stands on, or the bottom line
  of a shape such as a triangle or rectangle.
• Base (numbers) - The Base (or Radix) is the
  number of digits in a number system. The decimal
  number system that we use every day has 10 digits
  (0,1,2,3,4,5,6,7,8,9) and so it is Base-10. Base
  is also the number that is going to be raised to
  a power. Example in 8², 8 is the base

• Base Ten System is another name for the decimal
  number system that we use every day.
• Bi - A prefix meaning "two"
• Billion - Usually means a thousand millions.
  1,000 x 1,000,000 1,000,000,000 (A 1 followed
  by 9 zeros)
• Bisect or Bisector - To divide into two equal
  parts. You can bisect lines, angles, and more.
  The dividing line is called the "bisector"

13
Mathematical Terms

• Boundary - A line or border around the outside of
  a shape. It defines the space or area. Countries
  have borders, and so do triangles and circles,
  etc.
• Brackets - Are symbols used in pairs to group
  things together. Types of brackets include
  parentheses or "round brackets" ( ) "square
  brackets" or "box brackets" braces or "curly
  brackets" "angle brackets" lt gt
• Breadth - Means width
