Roman Numerals from 1000 to 1 million

Below are the key Roman numerals from 1000 to 1 million.

For numbers greater than 1000, the Romans sometimes used the `M` and sometimes used `bar I` either way it means the same thing.

Either way, for larger numbers, the Romans used an overline, which had the effect of multiplying the value by 1000.

`bar I`  1,000
`bar V`  5,000
`bar X`  10,000
`bar L`  50,000
`bar C`  100,000
`bar D`  500,000
`bar M` 1,000,000

Below are all the key numbers from 1000 to 1 million.

Note:
1000 = `bar I` or `M`
1001 = `bar II` or `MI`
1002 = `bar III` or `MII`
1003 = `bar IIII` or `MIII`
1004 = `bar IIV` or `MIV`

After the thousand you just count as normal, and that goes for all the numbers below.

When learning the numbers, always remember this sentence to help you along:

'I Value Xylophones Like Cows Do Milk'. 
`I=1`,  `V=5`,  `X=10`,  `L=50`,  `C=100`,  `D=500`,  `M=1000`
