| WHOLE NUMBER | ALSO CALLED COUNTING NUMBERS . ONE OF THE POSITIVE INTEGERS OR ZERO ; ANY OF THE NUMBER { 0, 1, 2, 3, … } |
| ESTIMATION | A WAY OF GETTING A " ROUGH IDEA " OF WHAT A SOLUTION TO A PROBLEM MIGHT BE BEFORE DOING THE EXACT CALCULATIONS |
| ROUNDING | A WAY OF ESTIMATING WHERE YOU TAKE THE NUMBER YOU ARE ESTIMATING ABOUT , AND FIND THE DIGIT IN THE PLACE TO THE RIGHT OF THE DIGIT THAT IS THE TARGET OF YOUR ESTIMATION . IF THE DIGIT TO THE RIGHT IS 5 OR MORE , THEN THE DIGIT IN THE PLACE THAT IS THE TARGET OF YOUR ESTIMATION IS INCREASED BY ONE . IF IT IS 4 OR LESS THEN THE DIGIT THAT IS THE TARGET OF YOUR ESTIMATION IS DCREASED BY ONE |
| FRACTION | A SMALL PART OR SEGMENT OF SOMETHING . IN MATH A NUMBER USUALL EXPRESSED SUCH AS a/b . IN ROUNDING , IF THE FRACTION IS LESS THAN 1/2 IT IS ROUNDED DOWN , IF IT IS 1/2 OR GREATER ( 3/4 AS AN EXAMPLE ) IT IS ROUNDED UP TO THE NEXT WHOLE NUMBER |
| MIXED NUMBER | A NUMBER REPRESENTED BY THE COMBINATION OF A WHOLE NUMBER AND A FRACTION > FOR EXAMPLE : 3 1/4 . IF THIS EXAMPLE WAS ROUNDED IT WOULD BE ROUNDED DOWN TO 3 ( WITH THE FRACTION BEING DROPPED ) BECAUSE THE 1/4 FRACTION IS LESS THAN 1/2 |
| ORDER OF OPERATIONS | MUST BE USED TO SIMPLIFY MATHEMATICAL EXPRESSIONS TO GET THE CORRECT ANSWER |
