Egyptians used math such as measurement and time. They used time by using clocks and calenders. They used measurements by recording the time, use rulers and use cubit. There are so many clocks and calendars. This essay is about how did they would use Math in Egypt.

The Egyptians recorded time by using calendars and clocks. They used sundials to measure time during daylight hours. There were sun clocks and water clocks. The water clock was a dual purpose instrument. These clocks were useful to the Egyptians to measure time and other things. There first calendar started in 2900 B.C. The calendars work it's way completely through the solar year and it ends up back where it started. **The lunar calendar consist of three seasons, each season last four months.** This calendar starts with a star spodet name Sirius. The solar calendar had ten days a week, 3 weeks a month, four months a season and three seasons plus five holy days equals a year.

The Egyptians used measurements their whole life. They would use rulers to record time during the daylight hours. Egyptians weights were based on a unit called a kite and cubit was an Egyptian standard measure based on the length and cubit was the basic unit of length. The weight of a kite varied period to period ranging all the way 4.5 to 29 grams. Egyptians measured time according to how long their rulers stayed in power. Cubit had originated in Egypt in 3000 B.C. thereafter became ubiquitous in the ancient world and the measure of cubit is 18 inches and it may sometimes be 21 inches. There was royal cubit and a regular cubit, the royal cubit was about 20 inches. Royal Cubit was based on the length of the arm from the elbow to the extended fingertips.

Egyptians used measurements mostly everywhere, they recorded time during daylight only. They had calendars and clocks used for different things. They would also have different names for different clocks and calendars. In measurements there was length and weight for length they would use cubit and for weight they would use this thing called a kite. There was two kinds of cubits, but they were kind of the same. They made different calendars because they had the calendars would start in a different dates.
