{!! app('mathcaptcha')->input() !!}

Display it wihtin Bootstrap as example:

<div class="form-group">
    <label for="mathgroup">Please solve the following math function: {{ app('mathcaptcha')->label() }}</label>
    {!! app('mathcaptcha')->input(['class' => 'form-control', 'id' => 'mathgroup']) !!}
    @if ($errors->has('mathcaptcha'))
        <span class="help-block">
            <strong>{{ $errors->first('mathcaptcha') }}</strong>
        </span>
    @endif
</div>

Looks like

Validation

Add 'mathcaptcha' => 'required|mathcaptcha' to rules array.

$this->validate($request, [
    'mathcaptcha' => 'required|mathcaptcha',
]);

Add corresponding translation string to your lang/validation.php files.

Reset

This package does not generate a new math question for each request. Once the form has been submited without validation erros you can reset the library to force generate a new question.

app('mathcaptcha')->reset();
