text is the number the portal wants. expression is the sum, so you can see the working.

For सत्ताईस + 8 the field text is 35 and expression is 27+8. The form on the portal wants 35. Logging 27+8 is how you explain a later dispute.

raw is the characters actually read, including the Devanagari word. When a report says the answer was wrong, raw shows whether the word or the digit was the weak part.

Do not type raw into the form. It is not the computed answer, and it may contain the operator.

Arithmetic without Hindi uses the same three fields. 14 + 9 comes back as text 23 and expression 14+9. The engine is math instead of hindi_math.
