:') Hi Jalal! welcome to GDSE.
Ahlan Wasahlan! ;') I presume you have Arabic language installed.
First go to CHARACTERS Panel, and watch your "Language", young man! ;') (default is Arabic).
In the future, for others:
With Arabic (and other RTL, right-to-left) languages always check
- Digits options
- Paragraph direction options (the buttons
above "Hyphenation" checkbox >>see attached image)
Weird directional stuff happens with Arabic language settings :'o (especially with numbers, marks, and Arabic and English combined!)
Don't be shy to ask for help, and also help when you can.
