Relationships

al-jabr → algebra: borrowing, documented. The source identifies this connection. Arabic mathematics: The everyday idea of restoring or completing is used for an operation on equations. The Arabic title contributes the later field name; this evidence does not date a bonesetting-to-algebra metaphor. English > Etymology, prose account

algebra → algebra: borrowing, documented. The source identifies this connection. English scope: The field name now covers abstract mathematical and logical systems as well as elementary equations. The Latin borrowing does not itself date these extensions. English > Etymology, prose account
