Four Fours Challenge
Build a math expression for every number from 1 to 100 using exactly four 4s and any math operators you know. Some numbers are easy; others will stretch your logic. PEMDAS rules.
Solved 0 / 100
Target
1
Type an expression using only the digit 4 and math operators.
Operator reference
+ - · add and subtract* or x · multiply/ · divide^ · power (e.g. 4^4 = 256)( ) · grouping for PEMDAS! · factorial (e.g. 4! = 24)√ · square root (prefix; √4 = 2)% · percent (e.g. 44% = 0.44). · decimal (e.g. .4 = 0.4)Multi-digit:
44 uses two 4s, 444 uses three.Goal: every expression must use the digit 4 exactly four times and evaluate to the target.
