Algebra:The branch of mathematics which extends operations, relations, and principles of literal (variable) quantities. Problem:1. n. a question to be answered or considered. EX. Do problems one through six in your books tonight. 2. n. a difficult point or situation or individual. 3. adj. describing a difficult situation. EX. My son is not a problem child. Formula:A formula is a sentence expressed symbolically showing the mathematical relationships among variables. Formula:Rule or method that is accepted as true and used over and over in common applications. Line:A continuous extent of length containing two or more points Equation:A mathematical sentence that uses the equal sign (=) to show that two expressions are equal. Equation:a mathematical sentence (e.g., 2x = 10) that equates one expression (2x) to another expression (10). Fraction:Any number that can be written in the form a/b where a and b are whole numbers and b cannot equal 0. Linear equation:An equation of the form ax+by=c; its graph is a line in the coordinate plane. Problem solving:Solving a problem using mathematics. Chart:What is it? A diagram that illustrates information in the form of a table, graph, or picture. Inequality:A mathematical sentence comparing two quantities that are not equal is called an inequality. Decimal:Based on 10 Example: the numbers we use in everyday life are decimal numbers, because there are 10 of them (0,1,2,3,4,5,6,7,8 and 9). Often "decimal number" is also used to mean a number that uses a decimal point followed by digits as a way of showing values less than one. Example: 1.9 is a decimal number (one and nine tenths) Simplify:To use the rules of arithmetic and algebra to rewrite an expression as simply as possible. Simultaneous equations:See under system of (simultanwous) equations. One step equation:An equation or inequality that can be solved in one step or action. First order differential equation:An ordinary differential equation of order 1. That is, a differential equation in which the highest derivative is a first derivative. For example, y' + xy = 1 is a first order differential equation. Algebraic expression:An expression that contains a variable alone or with numbers and operation symbols. Subtraction:an operation that tells the difference between two numbers or how many are left when some are taken away. Algebra:Algebra is the branch of mathematics that uses letters, symbols, and/or characters to represent numbers and express mathematical relationships. Those symbols are called variables. Fraction:Fractions are rational numbers which a ration of an two integers a/b (b cannot be 0). You can think of fractions as dividing a pie into pieces. Each piece of pie is a fraction of a pie. The bottom number b (the denominator) divides the size of the piece of pie and the top number (a) defines how many pieces of pie you have. Calculator:What is it? A machine for performing arithemtical calculations. Radical function:Any function whose equation is also a radical equation. 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. Square root:8 is called a square root of 64 because 8 x 8 = 64. But -8 is also a square root of 64 as -8 x -8 = 64. Every positive number has two square roots, one positive and one negative. 841 let say has 29 and -29 as its square roots because 29 x 29 = 841 and -29 x -29 = 841. In general m is called a square root of a number N if m x m = N, and then it will always be true that -m is also a square root. The Notation ??N can be used for the positive square root of a number. Note that the positive squa Negative integer:Any integer less than zero. Rational expression:An expression with fractions, especially when there is a variable in the denominator. The variable can not make the denominator equal to zero. Algebra:What is it? Algebra is the branch of mathematics that uses letters, symbols, and/or characters to represent numbers and express mathematical relationships. Those symbols are called variables. Super:A prefix that means that a mathematical structure is analogous to supersymmetry. Typically these structures have commuting and anticommmuting variables that are placed on an equal footing. For example, a supermanifold has anticommuting supercoordinates along with the usual commuting coordinates of its coordinate charts. Simple fraction:A fraction where the numerator and denominator are both integers. Also known as a common or vulgar fraction. 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. Exponent:a small figure placed to the upper-right of a number showing the number of times to multiply that number by itself Factoring:Finding what to multiply to get an expression. (Called Factorizing in British English.) Example: 2y+6 = 2(y+3), so the factors of 2y+6 are 2 and (y+3) Square root:The square root of x is the number that, when multiplied by itself, gives the number x . Algebra:area of math dealing in representing numbers with letters 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. Algebra:The study of equations using variables. At Capitan High School, the study of algebra is broken into Algebra 1 and Algebra 2. Expression a:collection of constants, variables, symbols of operations, and grouping symbols. Percent:A ratio or fraction where the denominator is always assumed to be 100. Equation:a balanced relationship between numbers and/or symbols. A mathematical sentence. Absolute value:The distance of a number from zero on a number line. Since distance is always thought of as positive, the absolute value of any number is always positive. Algebra:What is it? A branch of mathematics in which variables are substituted for unknown values to solve a particular problem. Solve an equation:To find the value of a variable that makes an equation true. Step function:A step function is a special type of function whose graph is a series of line segments. The graph of a step function looks like a series of small steps.
