Hello I need help solving a captcha that is in Thai. I do not speak Thai so I have no idea what is says. I uploaded the image here: http://imgur.com/zEvawU2
I was able to use an OCR extractor to get the text: หบีงบวกฆาม ใด้เทําใหรํ
I believe the answer to the captcha is a four letter word since that's all the input box allows for.
Your help is greatly appreciated!

หนึ่งบวกสามได้เท่าไหร่ = one plus three makes how much ? > the answer in English is FOUR

Well, either you wrote it worng , err wrong seeing as there is NO thai number spelled as ลิบหีา or it's really;
2000+สิบห้าได้เท่าไหร่
2000 plus 15 equals how much?
