Why are binary and decimal called positional numbering system?
Because they depend on the place value of numbers. For example, 101 = 1*b2 + 0*b + 1 where b is the base (2 or 10). There are only b different symbols or digits. Numbers that are greater than or equal to the base are displayed using the positional notation.
How do you add and subtract numbers using scientific notation?
To add or subtract numbers in scientific notation you first need to equalise their exponents. Having done that, you carry out the addition or subtraction on the significands and append the common exponent. Then you adjust the exponent so that the significand is between 1 and 10. For example, 1.234*104 - 2.34*102 (equalise exponents) = 123.4*102 - 2.34*102 (carry out subtraction) = (123.4-2.34)*102 = 121.06*102 (adjust exponent) = 1.2106*104
What is 800000000 m in scientific notation?
800000000 m = 8×10^8 m Changing units, it is also 8×10^5 km.
What is the for this problemgive the exponential notation and standard notation for 2x2x2x2x2?
The exponential notation and standard notation for 2x2x2x2x2 is:2532
What is the decimal conversion of the binary number 111?
To convert the binary number 111 to decimal, you can use the positional notation method. The binary number 111 represents the sum of 2^2 + 2^1 + 2^0, which equals 4 + 2 + 1. Therefore, the decimal conversion of the binary number 111 is 7.
What are positional muber system?
I think you meant positional number system or Positional Notation. In computer science when we talk about positional notation where talking about the binary(base 2) and hexadecimal(base 16) system. So for the most part a positional number system is a counting system. We for example use a base 10 counting system.
Why can't Roman Numerals be used always?
Roman numberals cannot be used for calculations more sophisticated than addition and subtraction because they lack the numeral zero and they lack positional notation. As a result theu are not easilly applied to multiplication, division, and fractions and cannot accomodate decimal notation.
What was the contribution of the Hindu Arabic system to the field of computation?
Base-10 decimal positional notation.
What is arithmetic operations on binary numbers?
The operations are the same as in decimal (+ - / x) the positional notation is somewhat different.
Who invented positional notation that would enable them to compute without abacus?
The Indian mathematician Aryabhata is credited with inventing positional notation, which allowed for more advanced computations without the need for an abacus. This system, known as the Hindu-Arabic numeral system, eventually spread to the Arab world and Europe, revolutionizing mathematics and arithmetic.
Why is 0.54 lager than 0.45?
We use Positional notation, 0.45 = 4 / 10 + 5 / 100 0.54 = 5 / 10 + 4 / 100 Therefore 0.54 is larger.
What is a weighted code?
Weighted code, also known as positional notation or place-value notation, is the method of encoding numbers. Its use of the same symbol for different orders of magnitude is what distinguishes it from other notations.
What math concept did the Mayans and Aztecs use?
They are credited with discovering the concept of zero.
How is 2123 expressed using the positional notation method?
2,123 = (2 x 1000) + (1 x 100) + (2 x 10) + (3 x 1)
What number represents 3542 seven converted to base 10 using the positional notation method?
3542 base 7 is equal to 1304 base 10 (decimal).
Is the Arabic number system a place value system?
Yes, it employs positional notation. It forms the basis of our decimal system, replacing the original Arabic symbols with Latin symbols.
What is the disadvantage of writing in scientific notation?
If you are adding or subtracting two numbers in scientific notation, you must rewrite one of the numbers to the same power of ten as the other, before performing the addition (or subtraction).
