| dividend | the number that is to be divided in a division problem |
| divisor | the number that divides the dividend |
| factor | a number multiplied by another number to find a product |
| greatest common factor | the greatest factor that two or more numbers have in common |
| least common multiple | the least number that is a common multiple of two or more numbers |
| prime factorization | a number written as the product of all its prime factors |
| prime number | a number that has exactly two factors 1 and itself |
| common denominator/CHAPTER 2 | numbers that are easy to compute with mentally |
| compatible numbers | a common multiple of two or more denominator |
| equivalent fractions | a number that names a part of a whole or part of a group |
| fraction | fractions that name the same amount or part |
| mixed number | a reciprocal of a number that is multiplied by that number resulting in a product of 1 |
| multiplicative inverse | a number that is made up of a whole number and a fraction |
| reciprocal | a fraction is in simplest form when the numerator and denominator have only 1 as a common factor |
| simplest form | two numbers are reciprocals of each other if their product equals 1 |
| absolute value/chapter 3- continued | a plane formed by a horizontal line called the x-axis and a vertical line called the y-axis |
| coordinate plane | the distance of an integer from zero on a number line |
| integers | a line that divides a figure into two halves that are reflections of each other |
| line of symmetry | the set of whole numbers and their opposites |
| line symmetry | any integer less than zero |
| negative integer | a figure has line symmetry if it can be folded about a line so that its two parts match exactly |
| opposites | a pair of numbers used to locate a point on a grid |
| ordered pair | two numbers that are the same` distance, but in opposite directions, from zero on a number line |
| origin-continued | any integer greater than zero |
| positive integer | the point where the two axes of a coordinate plane intersect: {0,0} |
| quadrants | any number that can be written as a ratio a/b where a and b are integers and b=0 |
| rational number | the four regions of the coordinate plane separated by the x- and y-axis |
| x-axis | the first number in an ordered pair; tells the distance to move right to left from {0,0} |
| x-coordinate | the horizontal number line on a coordinate plane |
| y-axis | the second number in an ordered pair; tells the distance to move up or down from [0,0] |
| y-coordinate | the vertical number line on a coordinate plane |
