Real and Complex. Real numbers are your everyday numbers that most people are familiar with and Complex numbers are Real numbers mixed with imaginary numbers. Of course this is a VERY BROAD oversimplification, and the question is somewhat vague in that there are other "types" of numbers that are used, but I think this is the answer you are looking for.

Complex numbers are a proper superset of real numbers. That is to say, real numbers are a proper subset of complex numbers.

No, not all. All numbers are Real Numbers. * * * * * All numbers are not real numbers: there are complex numbers and others. Also, all real number are not whole numbers. sqrt(2) or pi, for example are real numbers but not whole numbers.

numbers are used in every day life such as how old are you? whats 2+2? <forget that> if your talkin about real number as in |-26| = 26 then yeah forget it. I think that real numbers would be used in things like how far are you away from something for example you wouldn't need to know if you are - amount away or + just that you are a certain distance.

All integers are real numbers, but not all real numbers are integers.

examples: 1, 2, 0, -5, sqrt(2), pi etc. real numbers means numbers on the real plane. the opposite of real numbers are imaginary numbers which takes the format of ai, in which the i is the imaginary unit they do not exist on the real plane, but only on the imaginary plane. they can be found by square-rooting a negative number, e.g. sqrt(-4)=2i usually imaginary numbers are used with real numbers, with the format a+bi, and this is called complex numbers.

Yes, -1 and 1 are real numbers. Real numbers consist of irrational numbers, rational numbers and integers.
