Persian Numbers 20-100
The Persian number system is very simple and logical. Here we have shown you how to form all of the numbers between twenty and twenty nine. Exactly the same logic is applied to the 30's, 40's, 50's, 60's, 70's, 80's and 90's. For example, 'twenty three' is 'بیست و سه' (bist o se), and 'forty three' is 'چهل و سه' (chehel o se).
