Background

Mathematics, in English from Greek, "m th yama"; often abbreviated as "math"), is a discipline that studies concepts of quantity, structure, variation, space, and information, and is one of the formal sciences from a certain point of view. Mathematicians and philosophies have a range of views on the exact scope and definition of mathematics. In human historical development and social life, mathematics also plays an irreplaceable role and is an essential basic tool for learning and researching modern science and technology. The ruler is also called a measuring ruler, and is a tool for drawing line segments (especially straight) and measuring length. The scale is usually graduated to measure length. Some rulers are provided with a hole in the middle in a special shape such as a letter or a circle, so that a user can conveniently draw a picture, the ruler is generally used for measuring the length, and the ruler is generally divided into a measuring tape, a vernier caliper, a square, a ruler and a compass in mathematics and drawing, is a tool for drawing a circle or a string and is commonly used for drawing by a ruler.

The essential teaching aid is exactly the ruler in mathematical education, and the ruler divide into ruler, set square, and the compasses still need to use the compasses simultaneously, but these instrument function singleness all will carry a large amount of ruler teaching aids during every teaching for the mathematics is loaded down with trivial details of preparing lessons, and the use tool is inconvenient on class.
