- I am a 7th grade student (now, 2024) from Vietnam. I find the mistakes in the articles to fix and hope that everyone can have a great information while reading Wikipedia

- My first edit is the gamma function of 1/2-n. The last function is wrong, so:

$$\left(\frac{1}{2}-x\right)!=\frac{\left(\frac{1}{2}-x\right)!\sqrt{\pi}}{\left(-\frac{1}{2}\right)!} (x=n)$$ While the old version says

$$\left(\frac{1}{2}-x\right)!=\frac{\left(-\frac{1}{2}-x\right)!\sqrt{\pi}}{\left(-\frac{1}{2}\right)!}$$

As that, I hope everyone can understand and fix Wikipedia to be better
