Question 263054
I'm getting so confused....how will i BE ABLE TO tell the difference from Rational, Ilrational, whole , real. All this terminolgy is getting me confused. Thanks
Natural numbers::: 0,1,2,3,etc
Integer numbers::: positive and negative whole numbers
--------------------------------
Rational::::: any number that can be written as a fraction;
that included as the integers because 3 can be written as 3/1.
--------------------------------
Irrational:::: numbers that cannot written as fractions,
such as sqrt(2), sqrt(13) cube root(25) etc.
--------------------------------
Real::::: all the Rational and Irrational numbers are Real
------
Complex::: numbers that can be written in the form a + bi where
a and b are Real numbers.  So the Complex Numbers include all the
Real numbers because sqrt(2) can be written as sqrt(2)+0i
==================================================================
Use Google when/if you get confused.  It comes in time if you work at it.
