Hello, hugorganista!

I need help with the 4 4's problems.

I need to get the numbers 23 and 25 urgently.

I can use division, subtarction, multiplication, addition, power (exponent), and square root.

Of course, you can use the fraction-line . . . it's*division!*

If you like, we can write it: .

Is this allowed? . . .
