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. Quadratic equation:What is it? A polynomial equation of the second degree. The general form is ax2+bx+x=0, where a does not equal 0. Fraction:A fraction is a part of a whole, like a half, a third, a quarter, etc. Division:Division is an operation that tells us the number of groups that can be made out of a number of items or how many items will be in a group. The symbol ?? denotes division. Algebra:An algebra is a set which is both a ring and a vector space satisfying, of course various special properties or axioms. Adding:combining numbers Algebra:the branch of mathematics characterized by the use of variables and operations. Equation:A statement formed by placing an equals sign between two numerical or variable expressions. Polynomial:For now (and probably forever), you can just think of a polynomial as a bunch of blobs that are being added and subtracted. The blobs are just products of numbers and variables (letters) with exponents. Here's an example: Rationalize the denominator:The process of changing the denominator of a fraction from radical expression to rational number without changing the value of the expression. Variable:a symbol used to stand for a number. Least common denominator:The least common multiple of two or more denominators. Statistics:Statistics is also the mathematical study of the Likelihood and Probability of events occurring based on known quantitative Data or a collection of data. Compound inequality:What is it? Two or more inequalities that may have a common solution. Square root:the inverse or reverse of sqaring a number. For example, the square root of 100 is 10, because 10 x 10 = 100. Differential equation:A differential equation is an equation involving the first or higher derivatives of the function to be solved for. If the equation only involves first derivatives it is called an equation of order one, and so on. If only n-th powers of the derivatives are involved, the equation is said to have degree n. Equations of degree one are called linear. Equations in only one variable are called ordinary differential equations to distinguish them from partial differential equations. Simultaneous:1. as defined below. EX. Today's lecture is 'How To Sovle Simultaneous Equations.' Rational exponent:If the Power or the Exponent raised on a number is in the form `p/q`, where q ?? 0, then the number is said to have rational exponent. Factor:All the numbers that can be divided exactly into another number. Negative:n. a number less than zero; short for a negative number. Grade:- the tilt of a real-life object in relation to the horizontal, often used to determine how steep a hill is 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 al-jabr, meaning "restoration") was invented in the Middle East by Abu Ja'far Muhammad ibn Musa Al-Khwarizmi (born in Baghdad about AD 825) during the Middle Ages. Dimension:Length, breadth, width, height, thickness, depth. These are all dimensions. Algebra:a language that helps translate real-life situations into mathematical form so that we can analyze change and answer the question "What if? Number:Symbols used to express measurement of amount Variable:We call x a variable because it represents some number Least common multiple:The smallest non-zero number that is a multiple of two or more numbers. Algebra:Algebra also deals with symbols, relations, functions, and equations. Grade:The slope of a road, often represented as a percent or ratio. Calculator:n. a machine used for computation possibly having computer ability. Equation:An equation is a mathematical statement, in symbols, that two things are the same (or equivalent). Equations are written with an equal sign, as in 2 + 3 = 5 Answer:the solution to a problem. Calculator:A calculator is a machine that solves math problems. Algebra:An area of mathematics that uses numbers and letters. Factorization:Factorization is a method of writing numbers as the Product of their factors or divisors. 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. |
