### MEAP Preparation - Grade 7 Mathematics1.123 Integers - Positive and Negative Integers

 Natural Numbers: Natural Numbers are 1,2,3,4,5,................ Whole Numbers: Whole Numbers are 0,1,2,3,4,5,............... Positive Numbers: Positive numbers are, 1,2 ,3 ,4 ,5................. Negative Numbers: Negative numbers are, ............-3, -2, -1. They are read as negative three, negative two, negative one. Integers: A set containing the positive numbers, 1, 2, 3, 4, ...., and negative numbers,............-3, -2, -1, together with zero is called a set of integers. In other words, Integers are defined as set of whole numbers and their opposites. Z = {..., -3, -2, -1, 0, 1, 2, 3, ...} {1, 2, 3, . . .} is the set of positive integers { . . . -3, -2, -1} is the set of negative integers Zero is not positive nor negative, but is both. A positive integer has a (+) or addition sign in front of the number and looks like ( 5 or (+ 5). Also note that a positive integer doesn't need a sign. A negative integer has a (-) or negative sign in front of the number and looks like (- 7). A negative integer can be thought of as owing someone something. Think of it as (-8) means owing someone 8 items or things. Zero in neither positive or negative and is always larger than a negative integer. Positive integers are always larger than zero and any negative number. The larger a positive integer is, the bigger it is. Therefore a +7 is greater than a +5, written another way +7 > +5. The larger a negative integer the smaller is its value. Therefore, (-6) < (-5). Directions: Answer the following questions. Write your own examples of positive and negative integer problems.
