Arithmetic of Number Systems
A number system is a set of symbols used to represent values derived from a common base or radix. In a number, the value of each digit can be determined using digit, position of the digit in the number, and the base of the number system. The base is defined as the total number of digits are available in the number system. This is known as positional number system.Number SystemBaseDigit UsedBinary20, 1Octal80, 1, 2, 3, 4, 5, 6, 7Decimal100, 1, 2, 3, 4, 5, 6, 7, 8, 9Hexadecimal160, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, ...
Read MoreNegative Binary Numbers
Negative numbers can be distinguishable with the help of extra bit or flag called sign bit or sign flag in Binary number representation system for signed numbers. It is not possible to add minus or plus symbol in front of a binary number because a binary number can have only two symbol either 0 or 1 for each position or bit. That’s why we use this extra bit called sign bit or sign flag. The value of sign bit is 1 for negative binary numbers and 0 for positive numbers.When an integer binary number is positive, the sign is represented ...
Read MoreWhat is Vernier Calipers and How it is used for Measurement?
Measuring things and distances is one of the important concepts to learn when we are studying maths. For maximum uses, measuring scales do the work quite well and everyone is aware of it how to use one. But the measuring scale only provides a specific level of correctness and once you need exact measurements which lie between two spots on the scale it becomes difficult to get a correct reading without a bit of counterpart.Also measuring scales are very vulnerable to parallax mistakes which can cause a huge portion of the difference in readings from person to person which is ...
