Maths Captcha Problem

[cool.guy]

I am new to ZennoPoster, so would like to ask for a small help.

I was creating a new project in Project Maker and got stuck at a maths captcha.

Its simple text like 5+3=

And then there's a box for the solution.

Can anyone help me how can i simple make it automated to add those digits and put their sum in the next box?

Is their any option so that I can simply select the text and sum it Up?

Thanks for the help.

EDIT:

I found this php script for adding numbers.

<?php
echo "Please enter value 1 : ";
fscanf(STDIN, "%d\n", $value1); // reads number from STDIN standard input
echo "Please enter value 2 : ";
fscanf(STDIN, "%d\n", $value2);
echo "Answer : " .($value1 + $value2) . "\n";
?>

Can I use this to solve those simple maths text captcha?
OR there's already an option in Project Maker to do so?

use set-logic operation, and putting in place your maths captcha

First you need to parse the figures without the = (for example, as a result we must have 5 + 7). The result is then inserted into the macro the Java runtime.

Seems to be kinda cool but what if there would be different captchas everytime, so just by putting the JS Execute macro, will it work everytime properly and solve every different captcha?

HungryBulldozer gave you a template to look at to see how to handle it like normal captcha:

.

The problem with using JS like above is that they sometimes change them to foil bots. I was using the JS macro on some forum creation and then they changed to: 12 + 11 minus twelve= for example. Pulling it in as a captcha solves this because you have to manually input the answer. Just my experience.

But if you know that the site doesn't change it, then JS works great with different math problems.
