Use exactly four 4's to form every integer from 0 to 50, using only the operators +, −, ×, /, (brackets), . (decimal point), √ (square root) and ! (factorial). Example: 0 = 44 − 44

Four fours is a mathematical puzzle, the goal of which is to find the simplest mathematical expression for every whole number from 0 to some maximum, using only common mathematical symbols and the digit four. No other digit is allowed.

Jun 28, 2020 · We have four fours and we have four operations, and yet, we're limited. To illustrate this point, try to answer this question: There are exactly 11 other positive integers we can express with addition, multiplication, subtraction, division, and four fours. What are they? Hint: The largest is 256 = 4*4*4*4.

Use exactly four 4's to form every integer from 0 to 50, using only the operators +, −, ×, /, (brackets), . (decimal point), √ (square root) and ! (factorial).

"Given no more than 4 instances of the digit "4", represent all integers using a finite number of mathematical symbols and operators in common use." Notes on the Rules: Obviously negative integers can be represented if a positive number can. It can be proved that not all integers can be represented. ′ repeating decimal, eg: .4′ = .444444444...
