(1) The distance between x and x on the number line is equal to the distance between x^2 and x^2 (2) x ? x = 0, where ? represents one of the three operations addition, subtraction, or multiplication (1) x can take 0 or 1 or 1 in all the cases the distance between x and x on the number line is equal to the distance between x^2 and x^2 not sufficient (2) if x = 0 then ? represents any one of the operations if x=1 then ? represents addition if x=1 then ? represent subtraction not sufficient on combining also not sufficient E

Insuff Stmnt 2) if addition, x=1 if subtraction x=1 Hence E

This post was BOOKMARKED
For the first statement, distance between x and x is same as x^2 and x^2 let say x=1, 1, distance is 2 and 1^2 and 1^2, distance is 2 (GMAT number property, x^2= 1(x)^2 so 1^2= 1) insuff.
For the second statement, x? x = 0, ? represent + /  / x < does that mean only represent one of them, or all three? then x must be ve? xx= 0 I actually don't really understand the second statement. someone please explain, thank you
