## What are the different ways to represent a number?

Here are five ways to represent numbers that our students must know.

• Standard Form. This one might be obvious, but our students need to know how to write and read numbers in standard form.
• Word Form.
• Place Value Chart.
• Expanded Form.
• Pictorial or Object Representation.

### How do you represent a signed number?

The representation of a signed binary number is commonly referred to as the sign-magnitude notation and if the sign bit is “0”, the number is positive. If the sign bit is “1”, then the number is negative. When dealing with binary arithmetic operations, it is more convenient to use the complement of the negative number.

What are all the different types of numbers?

What does it look like?

Type of Number Example
Prime Number P=2,3,5,7,11,13,17,…
Composite Number 4,6,8,9,10,12,…
Whole Numbers W=0,1,2,3,4,…
Integers Z=…,−3,−2,−1,0,1,2,3,…

What is a represent number?

A number is a mathematical object used to count, measure, and label. More universally, individual numbers can be represented by symbols, called numerals; for example, “5” is a numeral that represents the number five.

## Can be represented in a signed magnitude format?

The magnitude is the size of the number irrespective of sign. For example, the numbers +13 and -13 both have a magnitude of 13. In Signed Magnitude Representation, the magnitude of a number is stored in N-1 bits and the sign is represented in the MSB, where N is the number of bits used to represent the entire number.

### What is a signed number in binary?

Signed binary numbers means that both positive and negative numbers may be represented. The most significant bit position is also used to represent sign for 1’s complement • 1’s complement of binary number N defined as (rn-1)-N.

Types of a Set

• Finite Set. A set which contains a definite number of elements is called a finite set.
• Infinite Set. A set which contains infinite number of elements is called an infinite set.
• Subset.
• Proper Subset.
• Universal Set.
