Integer

Integer

Integer is a combination of a negative integer, zero, and unanimously positive. Negative integers (..., -5, -4, -3, -2, -1). While the positive integers is (1, 2, 3, 4, 5, ... ... ... ....). So overall, are integers (... -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, ... ... ... ..)

1. Integer summation
24 (-15) = 24-15 = 9
13 19 = 42

2. Integer Reduction
24 - (-15) = 24 15 = 39
12-21 = -9

3. Integer multiplication
x = (positive x positive = positive)
x - = - (positive x negative = negative
- X = - (negative x positive = negative)
- X - = - (negative x negative = positive)

Example:

2 x 4 = 8
2 x (-4) = -8
-2 X 4 = -8
-2 X (-4) = 8

4. Multiplication and division with rounding to the nearest tens and hundreds

36 010: 6170 = 36 000: 6000 = 6
513 x 9 = 510 x 10 = 5100

5. Reappointment at Integer

ap x aq = ap q
ap: = ap-q aq
(Ap) q = apxq

Type Numbers

Original set of numbers
Original set of numbers is the set of numbers whose members is a positive integer.

Example: N = (1,2,3,4,5,6, ... ...)

The set of primes
The set of primes is the set of real numbers that can only be divided by itself and one, except the number 1.

Example: P = (2,3,5,7,11,13, ....)

The set of counting numbers
The set of counting numbers is the set of numbers whose members is a positive integer combined with a zero.

Example: C = (0,1,2,3,4,5,6, ....)

The set of integers
The set of integers is a set of numbers whose members are all integers, either negative, zero, and positive.

Example: B = (..., -3, -2, -1,0,1,2,3, ...)

The set of rational numbers
The set of rational numbers is a set of numbers that is a member-anggonya numbers which can be expressed as: p / q where p, q and q ¹ Î round 0 or can be expressed as a recurring decimal.

example: 0, -2, 2 / 7, 5, 2 / 11, etc.

The set of irrational numbers
The set of irrational numbers is the set of numbers whose members can not be expressed as a p / q or can not be expressed as a recurring decimal.

example: log 2, e, o7

The set of real numbers
The set of real numbers is the set whose members are a combination of a set of rational numbers and irrational.

example: log 10, 5 / 8, -3, 0, 3

The set of imaginary numbers
The set of imaginary numbers are sets of numbers whose members are i (imaginary unit) where i is a symbol of the new numbers are i ² = -1

example: i, 4i, 5i

The set of complex numbers
The set of complex numbers is a set of numbers whose members (a bi) where a, b Î R, i ² = -1, with a real part and b imaginary part.
