Math 1315-003 1.1Real Numbers Shelley Hamilton 1.1 Real Numbers: Real numbers are: 1,2,3,4 Whole Numbers are: 0,1,2,3,4 Rational Numbers are: where numbers can be written in the form p/q. But q cannot be equal to zero. So if q is a zero then it is not a rational number. Irrational numbers: all numbers that is not rational. Ex. Pie is irrational. Properties of real numbers: Commutative Prop.: a+b=b+a and ab=ba it doesn’t matter how you switch it, you will still get the same answers. Ex. 1+2=3 same as 2+1=3 and 5*6=30 same as 6*5=30. Associate Prop.: (a+b) +c = a+(b+c) and (ab)c = a(bc) Remember that the order of the numbers stays the same. Just the parentheses move.
