Inequalities Algebraic Conventions: Why is it incorrect to write "-2 > x > 2"?
Hi all
Wonder if someone could point me in the direct of a good resource that explains the algebraic conventions of writing inequalities?
For example can someone explain to me why it is incorrect to write the inequality -2 > x > 2 ? Is it something to do with a non-continuous interval? I presume it should be written as x > 2 or x < -2 ?
Also should x is greater than 2 be written as x > 2 or as 2 < x ?
Any hard and fast rules would be appreciated.
thanks
Jim
