In mathematics:

* x commonly represents an unknown variable

Even though any letter can be used, x is the most common by far

This usage can be traced back to the Arabic word šay’ شيء = “thing”, which in translated algebra texts and similar was taken into Old Spanish with the pronunciation “šei”, which was written xei, which was soon habitually abbreviated to x

(Spanish pronunciation of “x” has changed since

) But some sources say that this x is an abbreviation of Latin causa which was a translation of Arabic شيء

That started the habit of using letters to represent quantities in algebra

Yani diyor ki:

Bir İslam bilimcisi cebir kitabı yazarken bilinmeyeni “şey” olarak belirtmiş

Kitap İspanyolca’ya çevrilirken (Endülüs’te yani) “şey”i “xay” olarak çevirmişler

Sonra kısalıp x kalmış
