Which is greater negative 12 or negative 18?
-12 is larger than -18. Think of the negative numbers as moving right and left along a number line containing whole numbers.
Does every real number have two qualities - a sign and a distance from zero?
Yes. Real numbers are points along a continuous infinite number line with its midpoint at 0.
What includes natural numbers and zero?
Whole Numbers are only natural and zeroIntegers are positive, negative numbers and zeroRational Numbers include all Integers, along with any terminating, or repeating decimal numbers. (All fractions are rational numbers)Irrational Numbers include all non-repeating, continuous decimal numbers (Pi is a good example of an irrational number)Real Numbers include all of the aboveImaginary Numbers include any number that is not real. (iis the only example of an Imaginary Number that I know of)I know I went into MUCH more detail than asked for, but I figured why not.
What is negative 4 plus negative 8?
As you add negative numbers together, the answer moves further to the left along the number line, so when adding two negative numbers, it's straight addition and the answer is always (also) a negative number.
How do I write an interval notion and graph it...it is a set of real numbers that would be less than or equal to -4?
For an interval of numbers, two types of brackets are used, [] and (), the first signifies that interval includes the number before/after it and the latter indicate the interval includes everything upto that value.e.g.[0,2] indicates an interval of all real numbers from 0 to 2 including those numbers(-1,6) indicates an interval of all real numbers between -1 and 6 but not -1 and 6 themselves[5,12) indicates an interval of all real numbers from 5 upto but not including 12and (-9,-2] indicates an interval of all real numbers from -2 down to but not including -9.so, an interval of real numbers less than and equal to -4 would be (-­∞,-4], we use a ( for -∞ as, obviously, infinity can never be reached.To graph line intervals, we use a solid line along the interval and use filled circles, •, to signify that the point it is on is included in the interval, and empty circles, ○, to signify the point it is on is not included in the interval. So an interval of [5,12) would be drawn like this,•--------------------○5 6 7 8 9 10 11 12the drawing for (-­∞,-4] would simply be a straight solid line from the end of the negative side of the number line upto -4 with a • to show that -4 is included.
Defined real numbers?
Real numbers encompass any number along the number line, infinitely. Integers, whole numbers, natural numbers, etc. are are real numbers.
How do you are decimal numbers from smallest to largest in a number line?
Go from left to right along the number line.
Is 4.83 a real number?
The number 4.83 is a real number. Real numbers include all whole numbers, fractions, and decimals that can be represented as quantities along a continuous line.
What are counting or natural numbers?
Counting numbers are the positive integers: 1, 2, 3, and so on. Natural numbers are the counting numbers along with the number 0.
How can you use a number line to compare two numbers?
Draw the line (horizontally with positive numbers towards the right and negative numbers towards the left)) and mark the two numbers. The number which is further to the right along the line is greater than the other; alternatively, this can be expressed as: The number which is further to the left along the line is less than the other. If both numbers are the same point (mark) on the line, then they are equal.
Is the number 56 a rational number whole number natural number or irrational number?
56 is a rational whole natural number. Or to put it another way: 56 is a Natural number, but as all natural numbers are also whole numbers 56 is also a whole number, but as all whole numbers are also rational numbers 56 is also a rational number. Natural numbers are a [proper] subset of whole numbers; Whole numbers are a [proper] subset of rational numbers. The set of rational numbers along with the set of irrational numbers make up the set of real numbers
Why did Plato assume that the movement of the planets were along circles?
He was certain that all planets moved in a uniform, orderly manner, and his contemporaries figured that meant it had to be in circles because in circles there is no beginning and no end.
Are whole numbers counting numbers?
Yes, whole numbers are counting numbers.The term whole number does not have a consistent definition.Well the most used definition is "counting numbers along with zero".
How can you tell on a number line which numbers greater?
A number line is usually drawn in such a way that as you count,you move to the right along the number line.On a line drawn like that, greater numbers are farther to the right.(When you count, greater numbers come later.)
Is the number 81 a whole number?
Whole Number : Set of counting numbers along with zero. i.e. W = {0,1,2,3...} Therefore, 81 is a whole number.
When are two circles concentric?
When they have the same centre. As a consequence, the distance between the two circles, along any common radial ray, is a constant.
Illustrate the set of real numbers?
Real numbers include any number along the number line, infinitly. 24, -4/5, 21/8, -108, uneven squares, etc., are all real numbers.
