### Lloyd's Scribe Post

2. To model (-3) x (-5), Raini places 15 zero pairs on her desk.
a) Why did she use 15 zero pairs?
She used 15 zero pairs because she needed to remove 3 groups of -5.
b) What should she do next?
She should remove 3 groups of -5.

8. Write each expression as a repeated addition.
a) (+7) x (+2) 2+2+2+2+2+2+2
b) (+4) x (-9) -9+-9+-9+-9

13. Copy and complete each multiplication statement.
a) (+4) x (+6) = (+24)                    b) (+7) x (-2) = (-14)

c) (-1) x (+5) = (-5)                        d) (-8) x (-2) = (+16)

15. An aircraft descends at 3 m/s for 12 s. Use the multiplication of two integers to represent the situation. How far does the aircraft descend?
(+12) x (-3) = (-36)
The aircraft descends 36 m

1. Good job Lloyd! I liked how everything looks clear and organized. You also added a great video of how to do integers, just one thing maybe add a link to something good as well. Overall good job!
