  1. Math Vocabulary Julieta Rosales

  2. Integer • A member of the set of positive whole numbers

  3. Rational Number • A number capable of being expressed as an integer or a quotient of integers, excluding zero as a denominator.

  4. Scientific Notation • A method of writing or displaying numbers in terms of a decimal number between 1 and 10 multiplied by a power of 10. The scientific notation of 10,492, for example, is 1.0492 × 104.

  5. Perfect Square • A number made by squaring a whole number.16 is a perfect square because 42 = 16

  6. Irrational Number • A real number that cannot be written as a simple fraction - the decimal goes on forever without repeating.Example: Pi is an irrational number.

  7. Real Numbers • A number that is either rational or irrational rather than imaginary.

  8. Density Property • To measure the continuous values. A real number can be rational number or irrational number or it may be positive, negative or zero. It may also be algebraic or transcendental.

  9. Adjacent Angles • Either of the two angles that are formed by the intersection of two straight lines and lie on the same side of one line

  10. Coefficient • The number placed before a letter that represents a variable in algebra, e.g. the "3" of "3x" in the equation "3x = 6"

  11. Distance Formula • Any algebraic expression that gives the distance between two points in a particular coordinate system in a particular number of dimensions

  12. Domain • The set of values of the independent variable for which a function is defined

  13. Hypotenuse • The side opposite the right angle in a right-angled triangle

  14. Legs of a right Triangle • The sides of a triangle; - a name seldom used unless one of the sides is first distinguished by some appropriate term; as, the hypothenuse and two legs of a right-angled triangle.

  15. Range • The difference between the lowest and highest values.In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9, so the range is 9-3 = 6.Range can also mean all the output values of a function.

  16. Slope • How steep a straight line is.In this example the slope is 3/5 = 0.6

  17. Scientific Notation Where a number is written in two parts: First: just the digits (with the decimal point placed after the first digit),Followed by: ×10 to a power that would put the decimal point back where it should be.

  18. Prism • A solid object that has two identical ends and all flat sides.The cross section is the same all along its length.The shape of the ends give the prism a name, such as "triangular prism"

  19. Scatter Plot • A graph of plotted points that show the relationship between two sets of data.In this example, each dot represents one person's weight versus their height.

  20. Slope Intercept Form • The equation of a straight line in the form y = mx + b where m is the slope of the line and b is its y-intercept
