HW: "Why is your nose in the middle of your face?" Answer: it is the scenter It wasn't homework, but here are the answers to the even problems on the adding and subtracting integers w/s from class: 2. 2 22. 1 4. 2 24. - 5 6. - 5 26. - 11 8. - 17 28. 0 10. 2 30. 5 12. 0 32. 6 14. 7 34. 6 16. 9 36. - 4 18. 0 38. - 5 20. 12 40. 8 In class today students, who already know how to multiply and divide, learned one new piece of information - multiplying and dividing integers with the same sign yields a positive answer, while multiplying and dividing integers with different signs yields a negative answer. We practiced with problems from the blue textbook.
