I respectfully disagree. The voltage to a doorbell is either 16 or 24 volts always AC. The transformer has two terminals as noted. The bell has three terminals, One is common. The second is the two chime sounder and the third one is the one chime sounder. One connection on the transformer goes to the common on the bell. The other terminal on the transformer goes to both buttons. The return from each button goes to the remaining two terminals on the bell. Usually the front door goes to the two chime sounder and the back door goes to the one chime sounder. You may have to experiment to figure out which is the common. You will need assistance to push the buttons anyway so if that help is sighted you might as well have her read the labels on the bell box.
