Answer. Zero­Product Property: If AB=0 then A=0 or B=0. A (commutative) ring WITHOUT zero divisors is called an "Integral Domain". So: * a is 0, b is whetever it wants to be * b is 0, a is whatever it wants to be * a=b=0 If a and b are equal this is not true. Statement 2: If a^3 > 0, then a > 0. (x + b)(x + a) = 0 :. Here are two circles. (Substitution) If a = b, then b may be substituted for a in any mathematical statement without aﬀecting that statement’s truth value. because: 0*b = 0. a*0 = 0. If you have any real number A; you always have that: this means that the product between a number A and zero, is equal to zero, and this is for every number. Then I use that the integers a and b are comprised of natural numbers. ﷯ = 0 But the converse need not be true. 1. x2-12x = 0 2 2. 0 B. Assume for the sake of contradiction that a is not equal to 0 and b is not equal to 0, when you multiply a and b you get zero, but that is a contradiction because when you multiply two non zero numbers, the resulting number is also non-zero.

Statement 2 is not sufficient. Suppose that ab = 0. Lots of interesting rings DO have zero divisors, most notably matrices (non-commutative) and some modular arithmetics (commutative), like ordinary "clock" arithmetic with a 12-hour clock. Our experts are building a solution for this. > Fractions: 0/1 = (a/b)(c/d) means 1ac = 0bd ( =0 ). If AB = 0. then A=0 B=0. That is, if x is a nonzero number, then there is a number x^-1 such that x^-1 * x = 1. My proof is fairly straightforward. Nonetheless, for a "reasonably nice" system without zero divisors, we can "localize" at zero (if necessary, insert a zero along with negatives) by giving a reciprocal for every non-zero element, as well as introducing "1" if necessary.
