| 1 | 10 | 100 | 1000 | 1000000 | 1000000000 |

Here is a list of numbers. On the left are normal or "cardinal"
numbers. On the right are "ordinal" numbers, which we use to define a thing's
position in a series.

Note that in English, we usually separate the digits of numbers
over 999 with a comma (,). We count 3 digits from the right and insert a
comma, like this:
| < | - | - | - | < | - | - | - | |||
| 1 | , | 0 | 0 | 0 | one thousand | |||||
| 1 | , | 0 | 0 | 0 | , | 0 | 0 | 0 | one million | |
| 1 | 2 | , | 7 | 5 | 0 | , | 2 | 0 | 0 | twelve million, seven hundred and fifty thousand, two hundred |
We use a point (.) to indicate a decimal number, or to separate
dollars from cents, pounds from pennies and so on. Here are some examples:
| 0 | . | 1 | = | one tenth or 1/10 | ||||||||||||||||||||||||||||||||||||||||||
| 1 | . | 0 | = | one | ||||||||||||||||||||||||||||||||||||||||||
| 1 | , | 0 | 0 | 0 | = | one thousand | ||||||||||||||||||||||||||||||||||||||||
| 1 | , | 5 | 0 | 0 | . | 7 | 5 | = | one thousand five hundred and three quarters | |||||||||||||||||||||||||||||||||||||
| $ | 1 | . | 5 | 0 | = | one dollar and fifty cents | ||||||||||||||||||||||||||||||||||||||||
| $ | 7 | 0 | 0 | . | 0 | 0 | = | seven hundred dollars | ||||||||||||||||||||||||||||||||||||||
| £ | 3 | , | 5 | 0 | 0 | . | 0 | 1 | = |
three thousand five hundred pounds and one penny
