Read the passage and then choose the correct answers It is said that mathematics is the base of all other sciences, and that arithmetic, the science of numbers, is the base of mathematics. Numbers consist of whole numbers (integers) that are formed by the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 and by the combinations of them. For example, 247 — two hundred and forty seven — is a number formed by three digits. Parts of numbers smaller than 1 are sometimes expressed in terms of fraction, but in scientific usage they are given as decimals. This is because it is easier to perform the various mathematical operations if decimals are used instead of fractions. The main operations are: to add, subtract, multiply and divide; to square, cube, or raise to any other power; to take a square, cube, or any other root, and to find a ratio or proportion between pairs of numbers or a series of numbers. Thus, the decimal, or ten-scale, system is used for scientific purposes throughout the world, even in countries whose national systems of weights and measurements are based upon other scales. The other scale in general use nowadays is the binary, or two-scale, in which numbers are expressed by combinations of only two digits, 0 and 1. Thus, in the binary scale, 2 is expressed as 010, 3 is given as Oh, 4 is represented as 100, etc. This scale is perfectly adapted to the “off-on” pulse of electricity, so it is widely used in electronic computers. Because of its simplicity it is often called “the lazy schoolboy’s dream.”! 26. The main topic of the text is about _____ A. numbers B. mathematics C. arithmetic D. binary 27.
