Important MCQs Number System 1

The Post is about the MCQs Number System from Mathematics of Intermediate Part-I (First Year). Let us start with the Online MCQS Number System with Answers.

A numeral system is a way of expressing numbers; that is, it is a mathematical writing system or notation used to represent the numbers of a given set consistently by using either digits or other symbols. The same sequence of symbols may represent different numbers in different numeral systems.

Decimal Number System

The commonly used number system is the decimal positional numeral system. The decimal refers to 10 symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 to construct all numbers. In the decimal number system, there are a total of ten numbers/symbols. All other numbers such as 10, 11, 12, …, are all made from these 10 symbols/numbers.

In mathematics courses you have heard about number systems of whole numbers and real numbers, however, in the context of computer systems, the other types of number systems are (i) The decimal number system (Ten symbols or numbers), (ii) The binary number system (two symbols or numbers), (iii) The octal number system (eighth numbers of symbols) and, (iv) The hexadecimal number system (sixteen numbers or symbols).
