d) The product of two numbers, a and b is zero if and only if at least one of them is zero; e) For any given a, b e Rt satisfying a < b, one has a² < b°. [Recall that the symbol > is defined as follows: for r, y ER, r> y means r-y ER+%; f) Explain the scope of the requirement 1 + 0 contained in Axiom (iv) of the axiomatic description of real numbers.
