Face: The flat surfaces on a three-dimensional object. Get XML access to reach the best products. Example: the 4th root of 3 is 81 because 3 x 3 x 3 x 3 = 81. Now, to fight some ignorance: I vaguely recall a hardcore math doper saying that algebra is technically the study of polynomials and nothing else, but I think it’s generally accepted to include everything in that list. The exponent of 34 is 4. section is the place to go. A high school algebra class is kind of a general introduction to math. There’s a pretty complete list on your link of what math concepts you’ll need for the SAT. Right Triangle: A triangle with one right angle. This is familiar from the addition of hours on the face of a clock: if the hour hand is on 9 and is advanced 4 hours, it ends up on 1, as shown at the right. In my highschool Pre-Calculus and Advanced Algebra covered the same material, but Pre-Calc covered it in a semester, and AA covered it in a year.

Example: in the expression 3x + y, both y and x are the variables. Topics include exponential and logarithmic functions, algebra proofs, and 100 tough algebra word problems. basic statistics. Congruent shapes can be turned into one another with a flip, rotation, or turn. Adjugate. Parallelogram: A quadrilateral with two sets of opposite sides that are parallel.

Quadratic Equation: An equation that can be written with one side equal to 0. The center of a bell curve contains the highest value points. Pi: Pi is used to represent the ratio of a circumference of a circle to its diameter, denoted with the Greek symbol π. Some precalculus courses might differ with others in terms of content. Numerator: The top number in a fraction. Hypotenuse: The longest side of a right-angled triangle, always opposite to the right angle itself. But in high school? Abacus: An early counting tool used for basic arithmetic. http://www.collegeboard.com/student/testing/sat/prep_one/math_review.html. Formula: A rule that numerically describes the relationship between two or more variables. I never saw induction until pre-calc, and I kinda got the impression that a lot of people in my college introductory discrete math class had never seen it before. https://www.thefreedictionary.com/Advanced+Algebra+and+Trigonometry. Volume: A unit of measure describing how much space a substance occupies or the capacity of a container, provided in cubic units. Ray: A straight line with only one endpoint that extends infinitely. Hexagon: A six-sided and six-angled polygon. lines and planes That’s about as advanced as algebra gets in the pre-calculus years (HS or early college), but to a mathematician, “algebra” refers to something much broader and more general than just the standard operations on real or complex numbers (as ultrafilter pointed out). This section very briefly summarizes advanced algebra. ○ Boggle. Multiplication: Multiplication is the repeated addition of the same number denoted with the symbol x. A remainder can be expressed as an integer, fraction, or decimal. This is a glossary of common mathematical terms used in arithmetic, geometry, algebra, and statistics. Meaning, pronunciation, picture, example sentences, grammar, usage notes, synonyms and more. Yard: A unit of measure that is equal to approximately 91.5 centimeters or 3 feet. ), Pre-calculus at MECCA (Memphis Educational Computer Connectivity Alliance). Factor: A number that divides into another number exactly. Difference: The difference is the answer to a subtraction problem, in which one number is taken away from another. Adjugate. Addend: A number involved in an addition problem; numbers being added are called addends. Absolute Value: Always a positive number, absolute value refers to the distance of a number from 0. Operation: Refers to addition, subtraction, multiplication, or division. Rhombus: A parallelogram with four sides of equal length and no right angles. Chord: A segment joining two points on a circle. Equilateral: A term used to describe a shape whose sides are all of equal length. Prime Numbers: Prime numbers are integers greater than 1 that are only divisible by themselves and 1.

Net: A two-dimensional shape that can be turned into a two-dimensional object by gluing/taping and folding. Variable: A letter used to represent a numerical value in equations and expressions. Mixed Numbers: Mixed numbers refer to whole numbers combined with fractions or decimals. I don’t remember rigorously deriving the binomial theorem, but we definitely got familiar with it and used it. Line of Symmetry: A line that divides a figure into two equal shapes. Similar to a histogram, stem and leaf graphs organize intervals or groups of data. Number Line: A line whose points correspond to numbers. Base 10: Number system that assigns place value to numbers. BEDMAS stands for "Brackets, Exponents, Division, Multiplication, Addition, and Subtraction" and PEMDAS stands for "Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction". Absolute Maximum. Included in the course of study are real numbers, function and graphs, polynomials and rational functions, exponential and logarithmic functions, roots of polynomial equations, optimization, sequences and series, conic sections, systems of equations, limits. The purpose of this course is to prepare students for calculus by building the algebra skills that are required for calculus. I never got far enough in field theory to see how it’s done. trigonometry Bell Curve: The bell shape created when a line is plotted using data points for an item that meets the criteria of normal distribution.
