Because these subjects are interesting. When the Nile flooded most landmarks were destroyed or hard to locate. In order to reestablish your plot of land so you could farm it you had to know geometry to figure out where that parcel of land was. The tax collectors needed these subjects in order to collect appropriate taxes from land holders.
Geometry
Different subjects of math (e.g. algebra, geometry, algebra, number theory, calculus) that are integrated, or combined together.
Euler contributed to the subjects of geometry, calculus, trigonometry, and number theory. He standardized modern mathematical notation using Greek symbols that continue to be used today. He also contributed to the fields of astronomy, mechanics, optics, and acoustics, and made a major contribution to theoretical aerodynamics. He derived the continuity equation and the equations for the motion of an inviscid, incompressible fluid.
Usually when geometry is used outside of the subject of math, it doesn't seem like math. One use of geometry is in art, many people learn to draw a tree as a circle on top OS a rectangle, two geometric figures. Another use of geometry is in science, when many experiments are accompanied by drawings of the set-up or findings.
Arithmetic, Geometry, Music, and Astronomy
It consisted of arithmetic music, astronomy, and geometry.
numbers
In modern usage they are the study of number in this context.
The "seven liberal arts" are essentially the subjects taught in a classical education curriculum. This curriculum was particularly popular during the Medieval period, and was considered the curriculum that should be taught to a free man.These were:-Grammar-Rhetoric-Logic-Arithmetic-Geometry-Music, Harmonics, or Tuning Theory-Astronomy and CosmologyGrammar, rhetoric, and logic were part of the "artes sermocinales", or the science of language.Arithmetic, geometry, musics, harmonics, or tuning theory, astronomy and cosmology, were part of the "artes reales", or the scientific-mathematical discipline.
Greek scientists were interested in many subjects including, but not limited to: Agriculture Astronomy Biology Geometry Medicine Philosophy
Quadrivium (apex)
Quadrivium refers to the four subjects that were studied in school.
Quadrivium
Arithmetic
