(-9)(5)/-3=(-45/-3=15=-15
-45/-3 = +15
----------------
4-(-3)+1/2-2divided by(-2)=8/2+1=8/3=2 2/3
Not sure what you mean.
----------------------
9^2-(-6)^2=9^2-(-36)=81+36=117=-117
81 - 36 = 45
------------------
(-9)(5)/-3=(-45)/-3=15=-15
Same as #1
-------------
(-6)^2-4^2=(-36)-4^2=36+16=52=-2-52
36 - 16 = 20

%28-9%29%285%29%2F-3=-45%2F-3=15



9%5E2-%28-6%29%5E2=81-36=45....because %28-6%29%5E2=%28-6%29%28-6%29=36

%28-9%29%285%29%2F-3=%28-45%29%2F-3=15..........if dividing two negative numbers quotient will be positive

%28-6%29%5E2-4%5E2=%2836%29-4%5E2=36-16+=+20....be careful with sign..-4%5E2 is -4%2A4=-16...it is different if you have %28-4%29%5E2 which will be %28-4%29%2A%28-4%29=16
