The ancient Egyptian number system was composed of 7 symbols – a single stroke, a heel bone (upside-down smile), a coil of rope, a lotus plant, a finger, a frog, and a kneeling god.
With these 7 symbols, the clever Egyptians could add, subtract, multiple, and divide and count into the many millions! They even created a system of algebra, which helped them build the pyramids.
