| absolute value | a number's distance from zero on a number line |
| additive inverse property | a number and its additive inverse have a sum of zero |
| algebraic order of operations | the order of performing computations is paretheses first, then exponents, followed by multiplication and/or division, then adition and/or subtraction |
| associative property | the way in which three or more numbers are grouped for additionor multiplication does not change their sum or product |
| commutative property | the order in which two numbers are added or multiplied does not change their sum or product |
| composite number | a whole number that has more than two factors |
| concrete represenations of numbers | having a definite form or relating to an actual object |
| decimal number | any number written with a decimal point in the number.a decimal number falls between two whole numbers, decimal numbers smaller than one are sometimes called decimal fractions |
| distributive property | for any real numbers a,b,and,x |
| divisible | a term describing a number capable of being divided into equal parts without a remainder |
| effects of operations | the results of applying an operation to given numbers |
| equivalent forms ofa number | the same numbers in different forms |
| estimation | the use of ronding and/or other stratigies to deternine a reasonably accurate approximation, without calculating an exact answer |
| exponent (exponential form)( | the numberof times the base occursas a factor |
| factor | a number or expression that exactly dvides another number |
| fraction | any part of a whole s called a fraction |
| integers | the numbers in the set{...,-4,-3,-2,-1,0,1,2,3,4...} |
| inverse operations | an action that cancels a previously applied action. For example, subtraction is the inverse operation of addition |
| Irrational Number | a real number that cannot be expressed as a ratio of two numbers |
| multiples | the numbers that result from multiplying a given number by the set of whole numbers |
| multiplicative identity | the number one, that is, multiplying by ome does not change a number's value |
| multiplicative inverse | any two numbers with a product of one |
| natural numbers [counting numbers] | the numbers in the set {1,2,3,4,5...} |
| negitive exponent | used in scientific notation to designate a number smaller than one |
| number line | a line on which numbers can be written or visualized |
| operation | a mathamatical process, such as addition, subtraction, multiplication, division, raising to a power, or finding the square root |
| percent | a special-case ratio in which the second term is always 100. the ratio is written as a whole number followed by a percent sign |
| place value | the position of a single digit number or decimal number containing one or more digits |
| prime numbers | any whole number with only two factors, 1 and itself |
| radical | an expression that has a root (square root, cube root, ect.) Any root can be specified by an index number, b,a radical number without an index number is understood to be a square root |
| radical sign | the symbol used before a nomber to show that the number is a radicand |
| radicand | a number that appears with a radical sign |
| ratio | the comparison of two quantities |
| rational number | a real number that can be expressed as a ratio of two integers |
| real numbers | all raional numbers and irrational numbers |
| relative size | the sixe of one number in comparison to the size of another number or numbers |
| rule | a mathmatical expression that describes a pattern or relationship, or a written description of the pattern or relationship |
| scientific notation | a shorthand method of writing very large or very small numbers using exponents in which a number is expressed as the product of a power of 10 and a number that is greater than or equal to one |
| square root | a positive real number that can be multiplied by itself to produce a given number (ex. the square root of 144 is 12) |
| Whole Numbers | Numbers greater than 0. (ex 0,1,2,3.....) |
