Yes, numbers are read left to right in Arabic, just as they are in English.
While Arabic script is read from right to left, numerals are an exception to this rule. This applies regardless of whether you're using Eastern Arabic numerals (٠١٢٣٤٥٦٧٨٩) or Western Arabic numerals (0123456789). The order of magnitude is preserved; the leftmost digit represents the highest place value, as in English and most other languages.
For example, the number 123 is read "one hundred and twenty-three," even when written within Arabic text that is read from right to left.
