Full Answer

Spreadsheets are high-level computer programs that are used to store and analyze data. VisiCalc was the first spreadsheet program, and it was originally released for the Apple II personal computer in 1979. The spreadsheet is widely considered the first computer program that transformed the personal computer into a serious tool for business calculations and use. VisiCalc offered a small spreadsheet of only 254 rows by 63 columns, whereas contemporary spreadsheets can reach over 1 million rows by 16,000 columns.

Rows and columns are a convenient geometrical arranging tool to divide any data set, such as a grid on a map. In fact, latitude and longitude serve as rows and columns, respectively, on the geographical grid of a map of Earth and can be applied to any planetary body.

Rows and columns are also commonly used for describing seating arrangements, such as in a classroom. In mathematics, a matrix is an array of numbers, expressions or symbols that are arranged into rows and columns. Matrices are used in a wide variety of scientific and engineering fields.

  • Q:

    Why do some shapes tessellate and others not?

    A:

    Tessellations occur when a shape is repeated in an interlocking pattern that fully covers a flat surface, or plane, like the pieces of a puzzle. Some shapes cannot tessellate because they are not regular polygons or do not contain vertices (corner points). They therefore cannot be arranged on a plane without overlapping or leaving some space uncovered. Due to its rounded edges and lack of vertices, the circle is normally not tessellated.

  • Q:

    How many vertices does a square have?

    A:

    A square is a polygon with four vertices. The shape has four equal sides and four 90-degree angles; thus, it is called a regular quadrilateral. The sides meet in four corners, which are called vertices.

    What were the contributions of Rene Descartes?

    A:

    Rene Descartes, widely regarded as the father of modern philosophy, broke with the Aristotelian tradition, helping establish modern rationalism.
