Network+ Subnetting Step by Step Part Three ERROR

I believe there is an error in the binary calculations for this lesson. Working Octet is .46. The 16 place area should be 0 and not 1?
.46 - 32 = 14. 14 cannot be deducted from 16.

@wes-bryan can you confirm this, please. If this is wrong, I believe all the other calculations done for this lesson will be wrong too.

Hi Gilbert! @wes-bryan is on a much needed holiday. But I can take a look at this for you!

Can you give me the Network+ version number (006 or 007), the exact lesson name, and most importantly, the time stamp of the minute and second you see the goof.

THANKS!

Thank you so much for helping me to track that down! Yes - we have a goof there. @wes-bryan states we cannot do the subtraction - but he mistakenly leaves a 1 in that position. Just as you stated.

Thanks again - I will report this issue to Wes so he can correct it!

@Anthony-Sequeira I am sure @wes-bryan anticipated that so as to test us.. LOL

@Gilbert-Choo Great catch, and I wish I could say "I was testing the students," lol... but unfortunately that was not the case, goof up on my part. Thank you and I will most definitely add a correction!
