Mathematical Captcha Applier is a lightweight WordPress plugin that lets you easily apply a simple math-based captcha to form submit buttons on your website by specifying their CSS selector. Just provide a specific button’s CSS selector, and the plugin will display a captcha prompt before the action is completed. This could help to prevent spam and unwanted bot activity.
Features: 
– Add a mathematical captcha to form submit buttons (<code><input type="submit"></code> or <code><button type="submit"></code>) by specifying their CSS selector (ID or class). 
– Attempts to protect forms from automated submissions. 
– No external dependencies — lightweight and fast. 
– Simple configuration via the WordPress dashboard. 
– If JavaScript is disabled, this plugin will hide the selected buttons.
How It Works: 
When a user clicks the protected button, a small popup will appear asking them to solve a basic math problem (e.g., <code>5 + 3 = ?</code>). If answered correctly, the action will proceed.
If JavaScript is disabled in the browser, the plugin hides the selected submit button.
