I have lived in Saudi Arabia for nearly 3 years between 2011 and 2013. Once again, I am back in Saudi Arabia in 2019.
During my first visit, I picked up a bit of Arabic Language. However, my knowledge of Arabic Language is still very tiny. I am comfortable forming sentences with 1 Arabic word in it.
However, I am very comfortable with Arabic Numbers.
This video discusses Arabic Numbers in details.
Anyone visiting the Arab World or Northern Africa should find this information useful.
