Egyptian Maths, Engineering and Medicine
Describe the Egyptian achievement in mathematics and engineering: the Rhind Mathematical Papyrus shows calculations of area, volume, and fractions; the precision of pyramid alignment (within 0.05° of true north) required sophisticated surveying; and Egyptian medical papyri describe detailed anatomical knowledge and pharmacological remedies — placing Egypt as a major contributor to the early history of science and technology
What a learner can do afterwards
- Describes the Rhind Mathematical Papyrus as containing worked examples of arithmetic, geometry, and unit fractions
- Explains one specific engineering achievement: pyramid alignment, ramp logistics, or the accuracy of the Great Pyramid's dimensions
- Names at least one medical papyrus (e.g. Ebers Papyrus) and describes the type of medical knowledge it contains

More than 3,500 years ago, an Egyptian scribe named Ahmes copied out a scroll full of math problems. We call it the Rhind Mathematical Papyrus. It holds about 84 problems, and scribes used it to work out area, volume, and fractions.
Another problem gives a square field with sides 10 units long. Ahmes worked out the area the same way you would today: multiply the side by itself. 10 times 10 equals 100 square units. Farmers used this method to plan their crops.
Scribes could also run the method backwards. If a square field covered 25 square units, they asked which number times itself gives 25. Trying small numbers does the trick: 4 times 4 is 16, too small, and 5 times 5 is 25. So each side of that field is 5 units long.
Egyptian engineers also lined up huge stone monuments with high accuracy. The four sides of the Great Pyramid point toward true north, the exact direction of the North Pole, and they are off by less than 0.05 degrees. To get this right, surveyors watched the stars at night and used a plumb line, a string with a weight that hangs straight down, to keep walls perfectly vertical.
Egyptian doctors wrote down what they knew too. The Ebers Papyrus, another long scroll, describes the human body in detail and lists hundreds of remedies for illnesses, from stomach trouble to skin problems. Some of it reads like a spell, but much of it comes from careful observation of the body.
Egypt's scribes solved real math problems, its surveyors aligned monuments to true north with barely any error, and its doctors recorded detailed medical knowledge, all more than 3,500 years ago.
