Hyperbola:A conic section that can be thought of as an insideout ellipse. Formally, a hyperbola can be defined as follows: For two given points, the foci, a hyperbola is the locus of points such that the difference between the distances to each focus is constant. Math:Mathematics is the study of quantity, structure, space and change. It developed, through the use of abstraction and logical reasoning, from counting, calculation, measurement, and the study of the shapes and motions of physical objects. Percentage:A number out of one hundred. Calculator:n. a machine used for computation possibly having computer ability. Algebra:Everything you learn in arithmetic but with variables besides the numbers. Math:The grammar of size (amount), shape, and/or order. (according to Lancelot Hogben in Mathematics for the Million) The study and description of patterns A way to describe measurements of reality in symbols There are many other ways to define, describe, and use math. No one can name them all, but it is fun and deeply satisfying to investigate them. Line:A line is the straight path connecting two points and extending beyond the points in both directions. Math:The grammar of size (amount), shape, and/or order. (according to Lancelot Hogben in Mathematics for the Million) The study and description of patterns A way to describe measurements of reality in symbols There are many other ways to define, describe, and use math. No one can name them all, but it is fun and deeply satisfying to investigate them. Factoring:What is it? To break a number into its factors. Algebra:Algebra is the study of generalized arithmetic. In algebra, unknown numbers can be represented by letters in order to solve equations. For example, 4 + x = 10 is true for x=6. Algebra (originally called aljabr, meaning "restoration") was invented in the Middle East by Abu Ja'far Muhammad ibn Musa AlKhwarizmi (born in Baghdad about AD 825) during the Middle Ages. Addition:the adding of one quantity to another. Algebra:In arithmetic, you always know what numbers you are working with... Like 8  2 = 6. In algebra, one or more of these numbers is unknown. They usually put an "x" in for the mystery number. Can you guess what x is here? 7 + x = 15. Easy! Of course, it gets a little harder than that... But, it's not bad. Rational expression:Fractions whose numerators and denominators are polynomials. Divisible:Capable of being evenly divided by a number, without a remainder. Work:The physics term for the amount of energy required to move an object over a given path subject to a given force. Problem:A question to answer in mathematics.
