Typo in lesson 2


#1

Currently paragraph four reads:
"The binary number '1010' is 10 in base 2 because the 8's bit and the 2's bit are "on":"

It should be:
"The binary number 10 is '1010' in base 2 because the 8's bit and the 2's bit are "on":"


#2

This paragraph is correct
but
this one

is wrong

Read them both carefully


#3

I did miss a bit in the original paragraph but the original is still wrong.

"The binary number '1010' is 10 in base 10" would be correct and so would "The decimal number 10 is '1010' in base 2."

0b1010 does not equal 0b10 which is what the sentence says.


#4

@themikeswan
binary numbers are in base 2. That base 2 statement there refers to this 1010 number not the 10

what they are trying to say rephrased is

"The binary number '1010' is actually the decimal number 10 written in base 2 because the 8's bit and the 2's bit are "on":"


#5

Still poorly worded and needs to be edited. Perhaps the best version would be:

"The binary number '1010' is actually the decimal number ten written in base 2 because the 8's bit and the 2's bit are "on:"

That would remove all ambiguity. I've been counting in base 2, 8, & 16 since the early 90's so I understood the desired meaning but saw something that was unclear, my brain tried to make sense of it and changed 'binary' to 'decimal' originally which is what led to my first post.
