The Arabic Numbers
Arabic numerals (how the numbers look) are of two types: the ones used in most of the world which originate from Arabic and those which are used in Arabic today. Notice that, while Arabic itself is written right-to-left, the numbers remain written left-to-right:
I am 42 years old today! ↔ !اليوم عندي ٤٢ سنة
A pattern you might notice is that words containing a ١ or ٢ have word-forms that differ from any pattern

Numbers ١٩-١١ are constructed by placing "عشر" after the number, with the exception of ١١ and ١٢ which have special word-forms. Even though these numbers are written with two separate words, they are spoken as if they are one, so ة is pronounced as ت

Every other number under a thousand can be made placing the two words next to each other and adding the word "and", "-و", to the beginning of the next word; keep in mind that when reading numbers, the order is hundreds, ones, and then tens. Here are a few examples:
