Answer:
Step-by-step explanation:
Question 1
BC - AC and AB will provide different answers when compared to AC + CB and CA + BC. This is because AC means A multiplied by C (AC) or C multiplied by A (CA); thus means AC and CA are the same. Also, CB means C multiplied by B (CB) or B multiplied by C (BC); thus means CB and BC are the same.
Hence, Finding AC + CB will provide the same answer as finding CA + BC
However, finding BC - AC will provide different answer to finding AB because BC - AC means the multiplication of A and C is subtracted from the multiplication of B and C - the answer thereof will most likely be different from the multiplication of just A and B.
Question 2
From the explanation above,
The "different" answer is
Find BC - AC and Find AB
The "same" answer is
Find AC + CB and Find CA + BC
