Week 1 Homework Problems These are the homework Problems for the Part 1 and Part 2 Lecture Notes and the Just-in-Time Review Sections #1-#6 on pages 595 - 601 and #8 and #9 on page 603. I recommend that you work the problems for each of the Just-in-Time Reviews before attempting to work the problems below. The answers to all of those Just-in-Time Review exercises are listed in the back of your textbook. Problems 1-12 are like Just-in-Time Review #4 and Week-1-Part-1-Lecture-Notes.doc pages 1423. 1. 4 -2 = 2. - 4 -2 = 3. - 2 - 2 - 2 - 2= 4. -8 - 4 = 5. - 2 + 2 + - 4 = 6. -2 + 1 = 7. - 5 + 3 = 8. -5 - 8 = 9. (-5)(-1)(-1)(-1)(-1) = 10. 2 + - 10 = 11. 2 - 1(4) = 12. (-2)( -2)( -2) = If you need more work on addition, subtraction, multiplication and division problems like 1-12 above, there are more problems in a file under the Week 1 (Moodle) Lecture Material and Documents for Assignments in folder Lecture Materials for Week 1 - entitled \"Week-1-X-Additional Signed Number Problems(add-subtract-multiply-divide)\".

Use the order of operations (PEMDAS) to calculate an answer: 41. 5 * 3 + 6 * 32 + 4(2-6) Hint: Exponents are more important than multiplication so 32 = 3*3= 9 42. 5[3 - 4 * 32 + 4 * 2 - 2 ] 43. 16 2 * 4 2 * 4 44. 4(9 - 6)2 - 4 * 3 + 2 * 8 3+ 1 45. [4(9 - 6)2 + 4](3 - 2 * 2) 22 (-3 + 5) If you need more work on the order of operations like 41-45 above, there are more problems in a file under the Week 1 (Moodle) Lecture Material and Documents for Assignments in folder Lecture Materials for Week 1 - entitled \"Week-1-X-Extra Problems for the Order of Operation.doc\". This file has problems, and their answers are in the file \"Week-1-X-Extra Problems for the Order of Operations Answers.doc\". If you need to review fractions, there is a Word document under Lecture Notes and Materials entitled \"Week 1-Fraction Review.doc\". In 46-48, reduce the fractions to the simplest form. 46. 10/20 = 47. 28/32= 48. 15/24= In 49-50, add the fractions together. 49. 1/4 + 1/8+ 1/16= 50. 1/3 + 2/5 + 2/15=
