 Algebraic Expression A statement that contains a variable(s) and number(s) and at least one math operations Absolute Value Distance from 0, it is ALWAYS positive ex. |5|= 5 |-5|= 5 Distributive Propery For all real numbers a,b,and c, if a(b+c) then ab+ac to everything in parenthesis a(b-c)ab-cb Order of Operations The order in which mathimatical expressions must be evaluated. Simplify- do all possile steps Evalulate-substitue then simplify Anything to the zero power always equals one You can NOT add or subtract unlike terms BUT you can multiply or divide them Irrational Number Any number that cannot be expressed as a fraction Exponent Number of times the number is multiplied to itself Repeating Decimal A decimal that repeats in a pattern to infinity and is rational Numeric Expression A statement that contains numbers at one math operation Integer A whole number set of whole numbers and their oppisites including zero. (-4,-3,-2,-1,0,1,2) Solution All the value or values that make the statement true Perfect Square Integer that is squared ex. 4,9,25.. Equation An expression w/ an equal sign you cannot solve an expression you can an equation Fractions to Decimals ~If the bar covers the whole decmial put that place value minus one, ONLY WHEN BAR COVERS ALL! Base Number being raised to the power Signed Numbers Addition Same signs- add the value of the numbers and sum has the sign of the 2 numbers Diff. signs- forget the signs subtract smaller from larger answer takes the sign of the number further from 0. Arithmetic Sequence A series of numbers seperated by a common difference ex. 1,3,5 Signed Numbers Subtraction Add the oppisite Like Terms Same variable to the same power Whole Number Starts at zero and goes up Commutative Property For all real numbers a+b= b+a and a*b= b*a Doesn't matter which order Real Numbers The set of rational and irrational numbers Property of Oppisites For all real numbers a number and it's oppisite will always equal zero. a+(-a)=0 Natural Number Does NOT start at zero Variable a letter that takes the place of a number Terminating Decimal A decimal that stops and is rational Zero Product Property For all real numbers, anything times 0 is 0. 0*a=0 If the number of neg. signs are odd, the is answer is neg. If even the answer is pos. .. Geometric Sequence ex. 1,2,4,8 common ratio Rational Number Any number which can be expressed as a fraction Set A group of related information Signed Numbers Multiplicaton and Division Alike is postive Different os negative
