- 1. WRITING WHOLE AND ORDINAL NUMBERS IN WORDS NUMBERS AND NUMBSER SENSE (NNS) WHOLE NUMBERS WRITINWHOLEANDORDINALNUMBERSINWORDS JAMES DAVID D. MATOYLECTURE
- 2. Ordinal Numbers Ordinal means order. Ordinal numbers are whole numbers in order. 1. What place? What rank? What Position? 2. Whole numbers only; especial suffix or word ending 3. No fractions; no decimals. Example: 18th and 23rd but fifty – six and 4.9 are not. JAMES DAVID D. MATOYLECTURE WRITINWHOLEANDORDINALNUMBERSINWORDS
- 3. Suffix • word ending such as “st”, “nd”, “rd”“th” Superscript • Use in shorthand of writing an ordinal numbers • Small letters, written or printed a little upward, smaller and higher up or above the line • Example: 3rd, the suffix here is “rd” is written as superscript since it is above the line Ordinal Numbers JAMES DAVID D.

Editor's Notes
- Example Walkthroughs 1. Drawing Venn Diagrams With Sets Consider the following information: AAA = {1, 2, 3} BBB = {3, 4, 5} Universal Set UUU = {1, 2, 3, 4, 5, 6, 7} Draw a Venn Diagram describing the 3 sets. 2. Consider the following information: AAA = {1, 2, 3} BBB = {4, 5, 6} Universal Set UUU = {1, 2, 3, 4, 5, 6, 7} Draw a Venn Diagram describing the 3 sets. 3. Understanding How to Use Set Notation Consider the following information: Universal set UUU = {0, 1, 2, 3, 4, 5,...} Set NNN = {all natural numbers} Set AAA = {0} Set BBB = { } a) Is set NNN a finite set or an infinite set? What about set BBB ? b) List all disjoint sets, if any. c) Determine n(N)n(N)n(N) , n(A)n(A)n(A) if possible. d) Patsy made a statement saying that n(A)=n(B)n(A)=n(B)n(A)=n(B) . Is this true?
