Anthony just got a new drone with an HD camera and microphone, and he is eager to test it out. He connects his computer to its wireless live video stream, opens up his window, and flies it outside. On the video stream, Anthony can see his neighbor's house. He notices that one of their windows is open and a man and a woman are sitting at a table with their backs to the window. He decides to spy on them, so he moves the drone close to the window and has it hover there. The man and woman are talking about something as Anthony watches and listens to them on the video stream.

The man says "... so I had to write everything down and do the calculation myself." Then he hands a piece of paper to the woman and asks her, "Can you double check my math?" As the woman holds the piece of paper, it is entirely visible to the drone's camera, so Anthony zooms in on it. He sees the following equation:

34x4-44x6/528-24x11 = 101

The woman looks at the piece of paper for about 30 seconds and then says "Yeah, that's right, 101." The man says "Thanks", and then starts to get up from the table. Anthony quickly flies the drone back to his house.

After downloading the video recorded by the drone to his computer, Anthony plays it back. He looks at the equation again, and he can't figure out how the man and woman got 101. Can you explain how they did the calculation?

Hint: The calculation was done in base 10.
