What does "10000" in binary notation represent in ordinary (decimal) numbers?
In mathematics and digital electronics, a binary number is a number expressed in the binary numeral system or base-2 numeral system which represents numeric values using two different symbols: typically 0 (zero) and 1 (one). So "0" and "1" have the same meanings in binary and ordinary decimal notation. But "10" in binary means 2 in decimal, "100" means 2x2 (=4) in decimal. Continuing on, "1000" means 2x2x2 (=8) and "10000" means 2x2x2x2 (=16).

There are 10 types of people in the world. Those that know binary and those that don't.

Miscounted the number of zeros and got it wrong - terrible as I used to teach this stuff :-(

Easy if you know how number systems work (regardless of the base), but not well explained above.

I had to stop and think this one out. I do that on occasion.

Not into math I don't need lol

I knew binary when I took the college comuter classes in 1969-71, 52 years ago. To get this answer I just grabbed the first option. It seems that those particular memories are just dust on the shelves of my mind.

Thank you! The answer was as clear as mud to me! 😊💛

I don't understand this kind of maths.

w hen I get a hint for majority it brings up the incorrect answer

Binary is a "language" of numbers and you either get it or you don't!
Christopher J Voce
Interesting, I certainly did not known that.
Denise Currie
No Idea at all on this just made a (wrong) guess
Jorge Barron Y Ortiz
Piece of cake.
Yvonne Benn
Had to think about that one for a minute but got it right!
Janette Will
No idea.

I looked up the binary system to refresh my memory as I haven’t written code in more than 20 years. The definition actually gave me the answer, so I got the answer right but not without help.
