How about you show us what you have tried and explain where your difficulty is.

Apart from sounding a lot like a basic assignment the requirement is a bit vague. When should the addition occur? What should happen if the user types a non-number into a edit box?

Vague question, vague answer:

LineEdit3->setText( QString::number( LineEdit1->text().toInt() + LineEdit2->text().toInt() ) );

LineEdit3->setText( QString::number( LineEdit1->text().toInt() + LineEdit2->text().toInt() ) );

To copy to clipboard, switch view to plain text mode
