MC1011  algebrapalgebra:A mathematical language that uses symbols, usually letters that stand for unknowns, along with numbers. algebraic expressionalgebraic expression:An expression consisting of one or more numbers and variables along with one or more arithmetic operations. area Zarea:The number of square units needed to cover a surface enclosed by a geometric figure. base of an expressionGbase of an expression:In an expression of the form x^n, the base is x. composite numberOcomposite number:A whole number greater than 1 that has more than two factors. cube of a numbercube of a number:The product in which a number is a factor three times.Example: The cube of 2, or 2 cubed, is 8 because 2 2 2 = 8. domainUdomain:The set of the first numbers or abscissas of the ordered pairs in a relation.  equal sign$equal sign:A symbol of equality, =.  equationfequation:A mathematical sentence stating that two expressions are equal.Example:3 (7 + 8) = 9 5  evaluate*evaluate:Find the value of an expression.  exponentexponent:A number that indicates how many times a number or expression is to be multiplied by itself.Example:In the expression 5^3, the exponent is 3.  factorfactor:In an algebraic or numerical expression, the quantities being multiplied are called factors.Example: 3 and 11 are factors of 33.  formulaformula:An equation that states a rule for the relationship between certain quantities.Example: A = r^2 is the formula for finding the area of a circle. functionifunction:A relation in which exactly one element of the range is paired with each element of the domain.  function rule\function rule:An expression which describes the relationship between each input and output. function tablebfunction table:A table used to organize the input numbers, output numbers, and the function rule. numerical expressionnumerical expression:A mathematical expression that has a combination of numbers and at least one operation.4 + 2 3 is a numerical expression. order of operationsorder of operations:1. Evaluate expressions inside grouping symbols.2. Evaluate all powers.3. Do all multiplications and/or divisions from left to right.4. Do all additions and/or subtractions from left to right. power~power:An expression of the form x^n, read x to the nth power.Example: 7^4 is 7 raised to the fourth power, or 7 7 7 7. prime factorizationprime factorization:Expressing a composite number as a product of its prime factors.Example:The prime factorization of 63 is 3 3 7.  prime numberRprime number:A whole number, greater than 1, whose only factors are 1 and itself. productMproduct:The result obtained by multiplying two or more numbers or variables. solutionsolution:A replacement value for the variable in an open sentence. A value for the variable that makes an equation true.Example: The solution of 12 = x + 7 is 5. solve an equationlsolve an equation:The process of finding all values of the variable that make an equation a true statement. square of a numberysquare of a number:The product of a number and itself.Example: The square of 6, or 6 squared, is 36 because 6 6 = 36. variableTvariable:A letter or other symbol used to represent an unspecified number or value.
