Egyptians, the ago more than 5000 years lived, are called the first practical mathematicians. Measured against modern mathematics, However, their mathematics was still relatively simple. When the Egyptians began, to build pyramids,they still counted on their fingers. Nevertheless, they made a significant contribution, to develop mathematics. your priests, who were also mathematicians, directed the building of temples and pyramids, built as tombs for the pharaohs.
So these priests were also master builders and engineers; they drew blueprints, as they are still used today. These plans required precise measurements. The rough measurements, that were previously known, weren't enough for them. The Egyptian temples and pyramids created a new system of measurement.
