Example 4.1.

Here are some examples of numbers in Greek numerals:

A symbol '(called keraia) is used for indicating that the letters mean numbers, not words. Try the following:

1. What is χλ'?

 

2. What is τπθ'?

Therefore, all numbers from 1 to 999 can be written by the Greek numerals in the table. Then how about numbers that are greater than 999?

Example 4.2.

For the first nine letters (from α to θ), the same letters are reused to represent thousands, by applying the left keraia:

,α = 1000

,β = 2000

......

,θ = 9000

Here is an example:

How about numbers that are greater than 9999?

Example 4.3.

A new letter M is placed either next to or below a number from 1 to 9999 to indicate that the number is multiplied by 10000. For example:

1. αμM or

αμ M

= 140000

2. τμθM,βρμδ' = 349 × 10000 + 2 × 10000 + 100 + 40 + 4 = 3492144

Try the following:

1. What is ,ετπ'?

2. What is φλM,ζχιη?
