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