No, it will not be hard to do this. But to do this, we need to specify what arithmetic operations should be in captcha, and the max number in the string.
Re: Captcha with calculation- where to find them
I think image based captcha are difficult for user to read.
It will be good if you used a text based captcha with calculation.
A code in php can be written to generate a random arithmetic question.
SPam bots cannot do the calculation and thus we do not receive lot of spam.
I have added a captcha to my website using this good tutorial.
Hope this helps
