Leonidas was given the same numbers and rules and told to create an expression that equals $52$.
This is what he came up with:

$5\left(6+3\right) + 7$

Lola was also given the same numbers and rules and told to create an expression that equals $34$.
This is what she came up with:

$3\left(6+7\right) − 5$

The solution to this problem is similar to both Leonidas' and Lola's solutions.
