Let m be a positive integer. Define the set R= {0, 1, 2, ..., m-1). Define new operations and on R as follows: for elements a, b < R₁, ab== (a + b) mod m ab:= (ab) mod m where mod is the binary remainder operation (notes section 2.1). You may assume that R with the operations and O is a ring. i. What is the difference between the rings Rand Z? ii. Explain how the rings Rand Z are similar.

could you do this with clear steps please

Let m be a positive integer. Define the set R= {0, 1, 2, ..., m-1). Define new operations and on R as follows: for elements a, b = R,
a @b:= (a + b) mod m
a ob:= (ab) mod m
where mod is the binary remainder operation (notes section 2.1). You may assume that R with the operations and O is a ring.
i. What is the difference between the rings R and Zm?
ii. Explain how the rings R and Z are similar.
