| formula | an expression that describes a method for solving a certain type of problem Ex. some + more = total 2+8=10 |
| geometry | the study of shapes |
| point | an exact location |
| line | a straight collection of points extending in opposite directions without ending |
| line segment | a part of a line with two distinct endpoints |
| endpoints | the point at which a line segment ends |
| ray | begins at a point and continues without ending |
| horizontal | side to side |
| vertical | up and down: upright |
| oblique | a line segment that is neither horizontal or vertical |
| number line | a line showing numbers a certain distance from zero |
| integers | all counting numbers ....-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5,... |
| multiplication table | sequences for x's facts to show patterns |
| multiplication | repeated addition Ex. 3+3+3+3 = 3x4 |
| multiples | a product of counting by a number Ex. multiples of 2 = 2, 4, 6, 8, 10, etc. |
| factors | numbers that are multiplied together Ex. 2x3=6, the factors are 2 and 3 |
| product | the answer to a multiplication problem |
| Commutative Property of multiplication | when you multiply two or more numbers, order does not matter Ex. 2x3 = 3x2 |
| Property of Zero for Multiplication | When you multiply by zero, the product is always zero Ex. 8x0=0, 845x0=0 |
| Identity Property of multiplication | when you multiply by one, the number stays the same Ex. 8x1=8, 845x1=845 |
| division | separating a number into a given number of equal parts |
