The development of the calander shows they can divde the number of minutes hours days month etc in a year. Development of the pyramids shows geometry and engineering. look up to make sure.
The Egyptians developed the 'first calendar' based on the movement of 'star Sirius'.
<u>EXPLANATION:</u>
They applied the principles of astronomy in an effective manner to develop a an almost accurate calendar that was divided into 12 months, 365 days and 24 hours a day. This calendar is still used today.
The pyramids were big structures that were designed using the basis of mathematics and geometry.
The pyramids were built in a specific shape and using correct calculations for dimensions.
This showed that the Egyptians had knowledge of Math and Science and applied these concepts.
