Essential Question: How do I multiply and divide integers? Notes from Class: positive x positive= positive positive x negetive=negetive negetive x negetive=positive negetive x positive= negetive** The product is -30. 2** division sentences are= 30/6=5, 30/5=6 B1)** 32
 * A)1Complete the multiplication sentence -5x6= ?**
 * A)2 Write 2 division sentences that are equivalent to the multiplication sentence in part 1.
 * B1) Complete the multiplication sentence -8x-4=

B)2 2 division sentences that are equivalent to the sentence above are= 32/-4=-8. 32/-8=-4
 * B)2 write 2 division sentences that are equivalent to the multiplication sentence you found in part 1.

C) Write a division sentence that solves each problem. 1) ?x12= -132 1)** -132/12=-11 2)** -56/-8=7 3)** 132/-4=-33 4)** 8.84/5.2=1.7
 * 2) -8x?=-56
 * 3) ?x-4=132
 * 4) 5.2x?=-8.84

1) ?/-3=-8 1)** -8x-3=24 2)** 91/-7=-13 3)**11x-17= -187 4)19.95/9.5=2.1
 * D) Write division or multiplication sentences to solves the problems.
 * 2) 91/?=7
 * 3) ?/11=-17
 * 4)-19.95/?=9.5**


 * 4.4 Follow-Up

1) Find each quotient a)-121 /11=?** a)-11 b) -11 c)24 d) 24
 * b)121/-11=?**
 * c)-96/-4=?**
 * d)96/4=?**

2a) 6 2b) it helps me find -18/3=-6 as -6x3 is -18, 18/-3= -6 as -6x-3= 18, and -18/-3=6 as -3x6=-18
 * 2a) Find 18/3=**
 * 2b) how does your answer in part a help you to find -18/3, 18/-3, and -18/-3?**
