Question

I have a test on Monday...I need a fast way of memorizing all the numbers for each definition. Thanks!

Answer 1

I like the pictures that relate these as subsets of one another. http://neighbor.firn.edu/class/bradford/bradford_ms/geoffrey_cook/prealgSection4_6.html

But then, I'm a visual learner. If you are too, these diagrams will help. Otherwise, you may need to recite the relations in ascending order of inclusion, that is "natural, whole, integer, rational, irrational on the outside, together they make real" or you may need to draw the venn diagrams or write the lists with examples, over and over.
When you need to memorize anything, it is best to use the sensory mode that you prefer to learn. If you're a visual learner, you can learn by studying pictures and diagrams. If you're an audio learner, you can learn by saying it over and over, perhaps with a rhythm. If you're a kinesthetic learner, you can learn only by doing it, over and over. (We all learn by doing but the kinesthetic learner cannot learn any other way).
Figure out which one you are, and use that mode the most.

Answer 2

well what i did is, put an example next to each of them and go from there, quiz yourself untill your sure you know them
