The Description Form, Roster Form, and The Set-Builder Notation Form.
Roster method and set-builder notation. Example of Roster Method {a, b, c} {1, 2, 3} {2, 4, 6, 8, 10...} Example of Set-builder Notation: {x/x is a real number} {x/x is a letter from the English alphabet} {x/x is a multiple of 2}
Z=Integers; Rational numbers={a/b| a,b∈Z, b ≠ 0}.
Write the elements of the set in a roster form.
1 Integer comes from the Latin word meaning whole and untouched 2 Integers are whole rational numbers 3 Integers are the digits from 0 to 9 and a combination of these digits 4 Integers can be expressed as fractions with a denominator of 1 5 Integers of 1, 2, 3, 4, 5, ..... etc are the natural historical counting numbers 6 Integers can be positive numbers including 0 7 Integers can be negative numbers 8 Integers can be even numbers including 0 9 Integers can be odd numbers 10 Integers can be prime numbers having only 2 factors 11 Integers can be composite numbers having more than 2 factors 12 Integers can be increased by the powers of positive exponents 13 Integers to the power of 1 remain unchanged 14 Integers to the power of 0 are equal to 1 15 Integers on the number line are in ascending order 16 Integers 0 and 1 form the binary system 17 Integers can be perfect squares 18 Integers sometimes become irrational numbers when square rooted 19 Integer numbers are infinite 20 Integer 20 is equal to a score 21 Integers with many noughts can be expressed in scientific notation 22 Integers can be expressed in letters as in the Roman numeral system 23 Integer 23 is a prime number so it's prime time to say goodbye
A list of elements, separated by commas, enclosed in curly braces. Example: {3, 5, 7} is the set of single-digit odd prime numbers. Tricky Example: { { }, {3}, {5}, {7}, {3,5}, {3,7}, {5,7}, {3,5,7} } is the set of subsets of the set of single-digit odd prime numbers. Notice that every element of this set is itself a set. The roster notation allows the use of nested curly-braces to describe sets which have other sets as elements. Infinite set in roster notation: {1, 2, 3, ...} is the set of positive integers. The first few elements illustrate the pattern, and the ellipsis (three dots) indicate that the pattern continues indefinitely.
there are several ways of representing a set if our collection does not contain a very large Numbers's may use roster notation to describe it.
The Description Form, Roster Form, and The Set-Builder Notation Form.
(1) description (2) roster form (3) set-builder notation
a=[x;x2,4,6]
Roster method: A={1,2,3,4,5,6,7,8}Rule mathod: A={ ✖️.✖️ is a 1-8}
Roster method and set-builder notation. Example of Roster Method {a, b, c} {1, 2, 3} {2, 4, 6, 8, 10...} Example of Set-builder Notation: {x/x is a real number} {x/x is a letter from the English alphabet} {x/x is a multiple of 2}
what os the set of all integers divisible by 5
x/x g < 18
Z=Integers; Rational numbers={a/b| a,b∈Z, b ≠ 0}.
The first one is roster method or listing method. The second one is verbal description method and the third one is set builder notation.
