You don't have to look or travel far. They're always with you, right there in the
wonderful world of your imagination, ready to be called whenever you want them.
Just take a pencil and a scrap of paper and write down some digits. Write as many
or as few digits as you want, and if you're feeling a bit naughty or adventurous, add
a decimal point or a fraction bar to the mix. As long as you use only digits, with no
symbols, roots, or powers, the number you write down is a real, rational number,
and it was right there with you, all the time. There's no place like home.

It certainly can! All irrational numbers (numbers that can't be written as fractions, and in decimal form go endlessly without a pattern) are real (not divided by zero and not connected to the square root of a negative number).
