SUMMARY

The discussion centers on the mathematical challenge of using four zeros (0) and any mathematical operations to achieve the number 24. The correct solution is presented as (0! + 0! + 0! + 0!)! = 24, where 0! equals 1. Participants clarify that factorial notation applies after the value, emphasizing that 0! is indeed 1, not 0xFF. Misunderstandings regarding binary arithmetic and factorial notation are addressed, leading to a consensus on the correct interpretation.

PREREQUISITES
  • Understanding of factorial notation, specifically 0! = 1
  • Basic knowledge of mathematical operations and symbols
  • Familiarity with binary arithmetic concepts
  • Ability to interpret mathematical expressions and notation
NEXT STEPS
  • Research the properties and applications of factorials in combinatorics
  • Explore advanced mathematical operations involving zeros and factorials
  • Learn about binary arithmetic and its implications in mathematical puzzles
  • Investigate common mathematical brain teasers and their solutions
USEFUL FOR

Mathematicians, educators, students, and puzzle enthusiasts interested in factorials and mathematical problem-solving techniques.

I guess I don't have access to the brain teaser forum. This one kinda confused me:

Using “Only Four” ZEROS (0) and any Mathematical Operations/Symbols, to obtain the number 24.

Answer is (0! + 0! + 0! + 0!)! = 24


I know I am a bit rusty with hex/binary arithmatic but the answer i get with (0! + 0! + 0! + 0!)! is 3 assuming 8 bits:

0! = 0xFF and assuming no carry over:

0xFF + 0xFF = 0xFE

so (0xFF + 0xFF + 0xFF + 0xFF) = 0xFC

!0xFC = 3 Right? Where did I go wrong?

Yeah... I was wondering about the same thing.
0! is a factorial, just like n! for example with n
being any natural number. However 0! = 1.

Live long and prosper.
 
LOL you beat me to it, just got schooled from my wife of all people!

She said !0 would be 0xFF, but 0! = 1.

Factorial notation comes AFTER the value.

and 4! = 24.
