By an upper bound for a set A of real numbers, we mean any real number x such that every number a in A is smaller than or equal to x. If x is an upper bound for a set A and no number strictly smaller than x is an upper bound for A, then x is called sup A. Let A and B be two sets of ... form a+b where a is in A and b is in B. If z=sup C, then z < x+y z > x+y z=x+y nothing can be said

Suppose that $x_1, \dots x_n (n>2)$ are real numbers such that $x_i=-x_{n-i+1}$ for $1 \leq i \leq n$. Consider the sum $S=\Sigma \Sigma \Sigma^{x_ix_jx_k}$, where the summations are taken over all i,j,k : 1 $\leq$ i, j, k $\leq$ n and i,j,k are all distinct. Then $S$ equals $n! \: x_1, x_2 \dots x_n$ (n-3)(n-4) (n-3)(n-4)(n-5) none of the foregoing expressions

For any real number x, let [x] denote the largest integer less than or equal to x and <x>=x-[x], that is, the fractional part of x. For arbitrary real numbers x,y and z only one of the following statement is correct. Which one is it? [x+y+z]=[x]+[y]+[z] [x=y=z]=[x+y]+[z]=[x]+[y+z]=[x+z]+[y] <x+y+z> = y+z – [y+z]+<x> [x+y+z]=[x+y]+[z+<y+x>]

For a real number a, define $a^+=maxa, 0$. for example $2^+ = 2, (-3)^+=0$. Then for two real number a and b, the equality $(ab)^+ = (a^+)(b^+)$ holds if and only if both a and b are positive a and b have the same sign a=b=0 at least one of a and b is greater than or equals to 0
