We have a house over here with 0100 inside and this equals to 1111 to the power of 0101, minus 0001 divided by 7, the only number that's not in binary. And by the way, just remember that this has an equals sign, to the Roman numeral line above. Does that point to something?

# Try and solve the computer symbology part of the course challenge

It’s time again for the course challenge. Try and decipher the third line of the challenge:

IMPORTANT NOTE: According to strict operator priority rules, There should be extra brackets surrounding everything between the equals sign and the division sign. I can’t change that in the image so please add that when you’re solving the challenge on your paper. Mathematicians are known to forget brackets :-)

You can ask for hints in the discussion, but don’t give away the answer. That you’ll be able to see on the next step. Good Luck!
