1) -144 ÷ 9
= -16
-----------------------------------------------------------------------------------------------
2) [-15 - ( -10)] + 2
-15 + 10 +2
-5 + 2
= -3
----------------------------------------------------------------------------------------------
3) -30
----------------------------------------------------------------------------------------------
4) 180 - 45
= 135
---------------------------------------------------------------------------------------------
5) [-3] + (-3)
-3 - 3
= -6
----------------------------------------------------------------------------------------------
6) 180
---------------------------------------------------------------------------------------------
---------------------------- fill in blanks-------------------------------------------
7) corresponding angles
-------------------------------------------------------------------------------------------------
8) -10
-------------------------------------------------------------------------------------------------
9) 90 -65
=25
-------------------------------------------------------------------------------------------------
10) 90
-----------------------------------------------------------------------------------------------
---------------------------------answer the following questions--------------------
1) -23(36+24)= -2300, 892(-102+2) = 89200
------------------------------------------------------------------------------------------------
2) -2700 / 180
=15
------------------------------------------------------------------------------------------------
3) 15 x 24
= -360
------------------------------------------------------------------------------------------------
4) ∠a = ∠c
∠a + ∠ b = 180 linear pair
therefore ∠a = 90 ∠b=90 ∠c = 90
