A preview of "Operator Searches" Join Brilliant Premium

Operator searches are puzzles for equations that can be solved with a mix of logic, creativity, and number theory. These quizzes will explore different types of operator searches and the strategies for solving them.

For example, is it possible to make this equation true using only addition and subtraction?

\[2\, \square\, 3\, \square\, 4\, \square\, 5\, = 8\]

Using any operators (and parentheses if needed), can you make this true? Get creative!

\[1\, \square\, 1\, \square\, 1\, \square\, 1\, = 5\]
