WebProblem 16.11 Find all units, zero-divisors, and nilpotent elements in the rings Z Z, Z 3 Z 3, and Z 4 Z 6. SOLUTION; In general, if R 1 and R 2 are rings with unity, then so is R 1 R 2. The unity element is (1 R 1; 1 R 2). An element (a 1; a 2) in R 1 R 2 is a unit if and only if there is an element (b 1; b 2) in R 1 R 2 such that (a 1; a 2)(b ... WebJul 7, 2024 · 5.2: Division Algorithm. When we divide a positive integer (the dividend) by another positive integer (the divisor), we obtain a quotient. We multiply the quotient to the divisor, and subtract the product from the dividend to obtain the remainder. Such a division produces two results: a quotient and a remainder.
