To multiply 564 by 678, you would first multiply the units digits (4 and 8) to get 32. Write down the 2 and carry over the 3. Next, multiply the tens digits (6 and 6) to get 36, then add the carried over 3 to get 39. Write down the 9 and carry over the 3. Finally, multiply the hundreds digits (5 and 7) to get 35, then add the carried over 3 to get 38. Therefore, 564 times 678 is 382,392.

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.
