#### prep question

x=/= 0, |x|<1?

1. x/|x|
2. x<|x|

how would you solve this, without plugging in numbers (probably take forever)

ok .. here goes ...

mod(x) is the positive value of x ...

.... so x/mod(x) will be equal to either 1 or -1 ...

now the first statemnet says that x/mod(x) < x ... now x can take either fraction or intgere values and can either be negative or positive ...

now there are 2 cases for which the first statement is satisfied .... first when x>1 or when x is between -1 and 0 .... for the rest of the cases that is when x is between 0 and 1... and when x is less than -1... x/mod(x) will be greater than x ... so we have 2 values of x which satisfies the first condition ... in one case (when x is between -1 and 0) mod(x)<1.. and in the other case (when x is greater than 1) mod(x)>1 .. so statement one does not give a defnite answer .. so insufficient

the second statement says that x or < 1 .. so second statement is againd insufficient ...

..... now combine the 2 statements the second says that x is negative and the first says that x/mod(x)

... i am sorry if the explanation seems gibberish ...
