Evaluate: This word means "to calculate the numerical value". Face: The flat surfaces on a three-dimensional object. Multiplication: Multiplication is the repeated addition of the same number denoted with the symbol x. For example, x is the coefficient in the expression x(a + b) and 3 is the coefficient in the term 3y. Paragraph Writing Practice allows students to create a paragraph using their spelling or vocabulary words. This is often remembered with acronyms BEDMAS and PEMDAS. Volume: A unit of measure describing how much space a substance occupies or the capacity of a container, provided in cubic units. 4 x 3 is equal to 3 + 3 + 3 + 3. Addend: A number involved in an addition problem; numbers being added are called addends. Uniform can be used to describe size, texture, color, design, and more. Ordinal: Ordinal numbers give relative position in a set: first, second, third, etc. Normal Distribution: Also known as Gaussian distribution, normal distribution refers to a probability distribution that is reflected across the mean or center of a bell curve. The 8 is a constantterm, or simply a constant,because it has no variable part. High school math students need every advantage possible to make comprehending advanced math easier. Decimal: A real number on the base ten standard numbering system. X-Intercept: The value of x where a line or curve intersects the x-axis. Ray: A straight line with only one endpoint that extends infinitely. The greatest common factor of 10 and 20 is 10. Centimeter: A metric unit of measurement for length, abbreviated as cm. With over 2000 terms defined, this dictionary is ideal for supporting students who are studying mathematics or related subjects. The overlapping section contains information that is true of both sides or sets and the non-overlapping portions each represent a set and contain information that is only true of their set. Range: The difference between the maximum and minimum in a set of data. Angle Bisector: The line dividing an angle into two equal angles. Numeral: A written symbol denoting a number value. Isometric Paper, Math Charts, Grids, Graph Paper, How to Determine the Geometry of a Circle, Fifth Grade Math - 5th Grade Math Course of Study. Whole Number: A whole number is a positive integer. If nx = a, the logarithm of a, with n as the base, is x. Logarithm is the opposite of exponentiation. Many square roots are also irrational numbers. End Point: The "point" at which a line or curve ends. Multiple: The multiple of a number is the product of that number and any other whole number. Subtraction: The operation of finding the difference between two numbers or quantities by "taking away" one from the other. Common Factors: A factor shared by two or more numbers, common factors are numbers that divide exactly into two different numbers. The math vocabulary lists are based on the Common Core High School Math Standards. Complementary Angles: Two angles that together equal 90°. Polynomial: The sum of two or more monomials. Expressions: Symbols that represent numbers or operations between numbers. Vocabulary TestMe provides students with the opportunity to take a vocabulary test independently. Similar to a histogram, stem and leaf graphs organize intervals or groups of data. Tree Diagram: Used in probability to show all possible outcomes or combinations of an event. Variable: A letter used to represent a numerical value in equations and expressions. Event: This term often refers to an outcome of probability; it may answers question about the probability of one scenario happening over another. Integers: All whole numbers, positive or negative, including zero. Ellipse: An ellipse looks like a slightly flattened circle and is also known as a plane curve. Circumference: The complete distance around a circle or a square. Reflection: The mirror image of a shape or object, obtained from flipping the shape on an axis. X-Axis: The horizontal axis in a coordinate plane. Line: A straight infinite path joining an infinite number of points in both directions. Quadruple: To multiply or to be multiplied by 4. WhichWord? Example: the 4th root of 3 is 81 because 3 x 3 x 3 x 3 = 81. Trinomial: A polynomial with three terms. Equilateral: A term used to describe a shape whose sides are all of equal length. Math Dictionary. Quadratic Equation: An equation that can be written with one side equal to 0. This is a glossary of common mathematical terms used in arithmetic, geometry, algebra, and statistics.
