Document Summary

Lecture 1 number & words; repertory grid. Integers (e. g. -3, -2, -1, 0, 1, 2, 3 ) These numbers are used to count countable things, like fish. However, there are many uncountable things water. Another way to think of a number if a point on a linear continuum or a number line . The continuum is the family of real numbers. A real number is either rational or irrational number. Rational number can be written as a ratio of 2 integers. Every rational number ends after a finite number of digits (e. g. 1. 25) or, begins to repeat a sequence of digits (e. g. 10909 ) Irrational number does not end or repeat a sequence of digits (e. g. pi = It is the idea of a continuum of real numbers that underlies the process of measuring the world around us. Counting numbers = natural numbers, whole numbers, & integers. Measuring numbers = rational numbers, irrational numbers, & real numbers.
