This add-on will replace the default image captcha within Concrete5 with a simple math problem like:
What is 4 + 6?
The quesiton outputs as a field in your form and a correct answer must be provided to allow the form to be submitted.
After installing this add-on, you need to tell Concrete5 to use this new Captcha option. To do this, in your dashboard:
1. Go to System & Settings > Permissions & Access > Captcha Setup
2. Select "Simple Math Captcha" from the dropdown
3. Click Save
