Chapter: 1 / Q: M30 This problem appears in a middle-school mathematics textbook: Together Dan and Diane have $20. Together Diane and Donna have $15. How much do the three of them have in total? (Transition Mathematics, Second Edition, Scott Foresman Addison Wesley, 1998
Chapter: 1 / Q: T10 Technique D [629] asks you to formulate a definition of what it means for a whole number to be odd. What is your definition? (Don’t say \\the opposite of even.") Is 6 odd? Is 11 odd? Justify your answers by using your definition
Chapter: 1 / Q: T20 Explain why the second equation operation in Definition EO [13] requires that the scalar be nonzero, while in the third equation operation this restriction on the scalar is not present
Chapter: 1 / Q: M70 We have seen in this section that systems of linear equations have limited possibilities for solution sets, and we will shortly prove Theorem PSSLS
