Making Zero Pairs

-16 -5 +11 -2
+16 +5 -11 +2

+6 -10 -9 +3
-6 +10 +9 -3

-6 +2= -4
-6 -2= -8
-6 +10= +4
6-(-4)= 10
-2(-3)= 1
-3 - 6= -9
-3 - 2= -5

HW.
-3 (-7) = +4
-3 -7 = -10
3 -7 = 4
3 +7 = 10
-3 +7 = 4

Chapter 2: Multiplying Integers

(+2) x (+3) = +6
(2) x (3) = 6
(2) (3) = 6
If brackets are touching, they multiply
or
If a number is touching a bracket,it also multiply

(2) x (3) = 6
or
2 groups of (3) = 6
of means multiplying


(2) x (-3) = -6
or
2 groups of (-3) = -6


(-2) x (+3)
Remove 2 groups of (+3) (use zero pairs)


(-2) x (-3) = +6
^ remove 2 groups of (-3) = +6


Chapter 3: Dividing Integers

Partative Division - making parts




Quotative Division - sharing your total with groups



Chapter4: Order of Operation with Integers
To solve (+5) x (-3) + (-6) / (+3), I would first follow the BEDMAS. I'd put square brackets around (-6) / (+3). After, I would solve (+5) x (-3) and then I would add the two answers together and which would equal to -17.

(+5) x (-3) +[(-6) / (+3)] = ( -17)

(+5) x (-3) + (-2)

(-15) + (-2)

(-17)
