Other, lost works of al-Karaji's are known to have dealt with inderterminate algebra, arithmetic, inheritance algebra, and the construction of buildings. Another contained the first known explanation of the arithmetical (Pascal's) triangle; the passage in question survived through al-Sama'wal's Bahir (twelfth century) which heavily drew from the Badi.

However, the use of binomial coefficients by Islamic mathematicians of the eleventh century, in a context which had deep roots in Islamic mathematics, suggests strongly the table was a local discovery - most probably of al-Karaji."
Known for more than a millenium in Asia and Europe (cf. Burton [Bur'07]), the origins of the Pascal triangle are lost in the mist of time. In Chandahsāstra, the Hindu scholar Pingala has classified meters (chandas) or rhythm of poems that are closely allied to music (Bag [Bag'66]). He enumerated and counted the meters of a given length n that have exactly r syllables of a kind. In doing this, he obtained Meruprastāra (the stairway to the mythical mountain Meru). Then Halayudha (cca. 975) in Mṛta-Sañjīvanī, a text of commentaries on Pingala's Chandahsāstra, clearly described Meruprastāra as what is today known as the arithmetic triangle. Among those who considered the triangle before Pascal, we find: Al-Karaji (953-1029); Jia Xian (1010-1070), China; Al-Samawal al-Maghribi...
But these in the alternate areas, which are given, I observed were the same with the figures of which the several ascending powers of the number 11 consist, viz. , , , , , etc. that is, first 1; the second 1, 1; the third 1, 2, 1; the fourth 1, 3, 3, 1; the fifth 1, 4, 6, 4, 1, and so on.
