Answer 2

Answer:

We call the complete collection of numbers (i.e., every rational, as well as irrational, number) real numbers. They have the symbol R.

You can think of the real numbers as every possible decimal number. This includes all the rational numbers—i.e., 4, 3/5, 0.6783, and -86 are all decimal numbers. If we include all the irrational numbers, we can represent them with decimals that never terminate. For example 0.5784151727272… is a real number. (Note that when we use “…” after a decimal number, it means there are more digits on the right beyond where we truncated.)

With this foundation, we can now turn from numbers to some of the important things we can do with numbers. Tomorrow, we will start with the first of these: factoring.
