2. So you're saying you have to use the number 4 four times to get 23 and 25 by some method you mentioned?

YES THATS EXACTLY WHAT I NEED

4. I've been playing around with this for a minute, but before I think more, when you multiply, divide, etc... you can only use the number 4? No other numbers in any operations?

Like $4^2+2*4+\frac{4}{4}=25$

5. Yes But Im In 7th Grade Pre Algebra And I Dont Thnk We Can Use Those Symbols. Like The Fraction Symbols

6. And U Cant Use 2

$25 \:=\:\left(4 + \frac{4}{4}\right)^{\sqrt{4}}$

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

If you like, we can write it: . $\bigg[4 + (4 \div 4)\bigg]^{\sqrt{4}}$

Is this allowed? . . . $23\;=\;\frac{44 + \sqrt{4}}{\sqrt{4}}$

8. This is a pretty good four fours site I found from a wikipedia reference:
