Why is paper an important invention?
Paper is considered to be a very important invention. This is because paper has helped many people communicate with each other.
Paper is an important invention because it replaced expensive parchment and papyrus as the storage medium of writing. Due to the inexpensiveness of paper and its effectiveness as a writing medium, it was possible to produce a significantly larger amount of books and to produce and distribute knowledge farther, cheaper, and faster.
Algebra was not an important invention to Islam as a religion. It was an important invention in mathematics that was discovered by a Muslim (Al-Khwarizmi). Algebra is important in mathematics because it establishes the ability to perform mathematical operations even if some or all of the quantities are unknown.
