The announcer says the numbers out loud :

first, just numbers, then numbers from 10 to 20, etc. - It's getting harder and harder.

       And you must correctly recognize the number and type it on the on-screen numeric keypad.

       The announcer girl can only help you with a simple gesture: within the framework of ASL - the American signal language. This language is used by the "English-speaking" deaf-mute. But, as soon as you get comfortable, you need to turn off the gestures and in future training use only your hearing.
