 * __**  ﻿ ﻿ ﻿ ﻿ **__** Variable ﻿- A symble used to represent a nonspecific number. Any letter used in an equation. x,y,k,m,..... **
 * ** ﻿Algebrac Exspression ﻿- Consistes of 1 or more variables and 1 or more arithmetic operations. **
 * ** ﻿Factors ﻿- The numbers being multipled in an exspression. **
 * ** ﻿Product ﻿- The resalt of an exspression. **
 * ** ﻿Power ﻿- A number with an expoint. **
 * ** ﻿Base ﻿- The number that isn't the expoint in the power. **
 * ** ﻿Expoint ﻿- The number of times you multiply the base. **
 * ** ﻿Evaluate ﻿- To find the answer. **
 * ** Writing algebrac exspression= example- 8 more then x. 8+x, 7 times m to the 5th power. 7m expoint 5. **
 * __** ﻿ ﻿ ﻿ **__** Order of Operations ﻿- A rule that tells you in what order to solve a problem. **
 * 1) ** Solve information in grouping symbles **
 * 2) ** Solve for expoints **
 * 3) ** Solve all division and multiplication **
 * 4) ** Solve all addition and subtraction **
 * ** example- 5+6(4-3)/3*8= **
 * 1) ** First do 4-3=1 **
 * 2) ** Then do 6*1=6, 6/3=2, and 2*8=16 **
 * 3) ** Then do 5+16=21 **

 * Open sentanc﻿e ﻿- A mathe statment with with 1 or more variables.
 * Solving an open sentance ﻿- The process of figuring out the amount of a vaireable.
 * Solution ﻿- The amount you replace the vaireable with.
 * Equation ﻿- Any math sentance contaning =.
 * Replacment set ﻿- A set of numbers where the variable can be chosen.
 * Set ﻿- A collection of objects or numbers.
 * Element ﻿- Any object or number in a set.
 * Solution Set ﻿- The set of elements from the replacement set that makes the open sentance true.
 * Inequalty ﻿- An open sentance that contanes <,>,
 * Additive identity - 0, because anything plus it equals its self
 * Multiple idenity ﻿- 1
 * Multipicative property of Zero ﻿- anything times 0=0.
 * Multiplcative inverse or resipricals ﻿- any number whos prodect is 1
 * Closed property ﻿- When a set of whole numbers equale a whole number

 * Distributive property ﻿- when you can move numbers in a problem around and get the same answer.
 * Term ﻿- a number, variable, product, or qustiont
 * Like term ﻿- numbers that have the same variable
 * Equvilent expresion ﻿- a number that donets the same number, 5n+7n=12n
 * Simplest form ﻿- when a number can't be simplifed any more
 * Coffidental ﻿- the number attached to the varaibles, 17 in 17xyn.
 * Communitive Property ﻿- when you can move numbers around and get the same answer. 1+2=2+1
 * Assositive Property ﻿- The way you group 3 or more numbers
 * Conditional reasoning ﻿- if A then B
 * Hypothesis ﻿- if in if then because
 * Conclusion ﻿- then in if then because
 * Deductive Reasing ﻿- Using facts to come up with a vaild answer
 * Counterexample ﻿ ﻿ ﻿- a specific case in which the statment is false.
 * Function ﻿- a relationship between input and output
 * Coordinate system ﻿- graphing a function
 * Origin ﻿- 0,0
 * Independent ﻿- doesn't matter, domin consists of all these numbers
 * Dependent﻿ ﻿- does matter, Range consists of all of theres numbers
