Greatest Common Factor – The largest number common to each set of factors that divides both numbers exactly.

E.g., the greatest common factor of 10 and 20 is 10.

Hyperbola – One type of conic section. The hyperbola is the set of all points in a plane. The difference of whose distance from two fixed points in the plane is the positive constant.

Irrational – A number that cannot be represented as a decimal or as a fraction. A number like pi is irrational because it contains an infinite number of digits that keep repeating, many square roots are irrational numbers.

Logic – Sound reasoning and the formal laws of reasoning. Logarithm – A power to which a base, [actually 10] must be raised to produce a given number the millionaire next door summary. If nx = a, the logarithm of a, with n as the base, is x.

Median – The Median is the ‘middle value’ in your list or series of numbers eur usd converter. When the totals of the list are odd, the median is the middle entry in the list after sorting the list into increasing order. When the totals of the list are even, the median is equal to the sum of the two middle (after sorting the list into increasing order) numbers divided by two.

Parabola – A type of curve, any point of which is equally distant from a fixed point, called the focus, and a fixed straight line, called the directrix.

Perimeter – The total distance around the outside of a polygon. The total distance around is obtained by adding together the units of measure from each side.

Quadrant – One quarter ( qua) of the plane on the Cartesian coordinate system numbers in binary. The plane is divided into 4 sections, each section is called a quadrant.

Quadratic Equation – An equation that can be written with one side equal to 0 usd euro converter. Asks you to find the quadratic polynomial that is equal to zero.

Radius – A line segment from the center of a circle to any point on the circle. Or the line from the center of a sphere to any point on the outside edge of the sphere. The radius is the distance from the center of a circle/sphere to the outside edge.

Ratio – The relation between to quantities. Ratios can be expressed in words, fractions, decimals or percents usd to php exchange rate today. E.g., the ratio given when a team wins 4 out of 6 games can be said a 4:6 or four out of six or 4/6.

Square Root- To square a number, you multiply it by itself. The square root of a number is the value of the number when multiplied by itself, gives you the original number. For instance 12 squared is 144, the square root of 144 is 12.

Translation – A term used in geometry. Often called a slide. The figure or shape is moved from each point of the figure/shape in the same direction and distance.

Variable – When a letter is used to represent a number or number in equations and or expressions. E.g., in 3x + y, both y and x are the variables.

Venn Diagram – A Venn diagram is often two circles (can be other shapes) that overlap. The overlapping part usually contains information that is pertinent to the labels on both sides of the Venn diagram. For instance: one circle could be labeled ‘Odd Numbers’, the other circle could be labeled ‘Two Digit Numbers’ the overlapping portion must contain numbers that are odd and have two digits british pound to usd history. Thus, the overlapping portions shows the relationship between the sets. ( Can be more than 2 circles.)

Vertex- A point of intersection where two (or more) rays meet, often called the corner. Wherever sides or edges meet on polygons or shapes. The point of a cone, the corners of cubes or squares.

Whole Number – A whole number doesn’t contain a fraction. A whole number is a positive integer which has 1 or more units and can be positive or negative.
