Numbers

Numbers are our way to quantify, label, and organize the world around us in a logical manner. However, the systems used to obtain this goal differ geographically, historically, and by relative utility. All questions pertaining to numbers, including historic labeling systems, bases of numerical systems, constants, and the various ways they're grouped together, should be placed into this category.

What is the square number of 1500 and 1600?

The square of 1,500 is 2,250,000 .

The square of 1,600 is 2,560,000 .

There's no such thing as the "square number of 1500 and 1600".

Is 0.313111331 a rational or irrational number?

It is rational. An irrational number is a number that you cannot define by a fraction or a decimal. Since you wrote it as a decimal, it is rational.

Is it ever possible to increase a numbers value by adding a decimal?

Yes...thats how math works

Decimal : 0.00001

Number : 1

Decimal + Number = 1.00001

Where

1.00001 > 1

How much is seventy hundred?

seventy hundred is the same as seven thousand (7000)

Is 99 an odd number or an even number?

99 is an even number because all even numbers end with or start with; 1,3,5,7,and 9

Which operation of rational numbers lets you add all the numerators then copy the denominator?

Operations on rational numbers refer to the mathematical operations carrying out on two or more rational numbers. A rational number is a number that is of the form p/q, where: p and q are integers, q ≠ 0. Some examples of rational numbers are: 1/2, −3/4, 0.3 (or) 3/10, −0.7 (or) −7/10, etc.

We know about fractions and how different operators can be used on different fractions. All the rules and principles that apply to fractions can also be applied to rational numbers. The one thing that we need to remember is that rational numbers also include negatives. So, while 1/5 is a rational number, it is true that −1/5 is also a rational number. There are four basic arithmetic operations with rational numbers: addition, subtraction, multiplication, and division.

What is nine is less than a number plus 1?

It depends on what other number you are using. If you want to use the number 11, the answer would be 3.

Are there classes of irrational numbers Example would be is pi a different type irrational number from the square root of 2?

This is an interesting question that has actually been studied with the concept of irrationality measure. Consider a real number x. For a positive number y, there may exist pairs (p, q) of positive integers with q > 1 such that 0 < abs(x - p/q) < 1/qy. As y increases, 1/qy approaches 0.

What we want to consider is those numbers y such that there exist infinitely many pairs (p, q) satisfying the above criteria. Specifically, let z be the least upper bound of the set of all such y. Then z is the irrationality measure of x.

Under this definition, the irrationality of a rational number is 1, the irrationality of an irrational algebraic number (an algebraic number is a number which is a root of a non-zero polynomial with integer coefficients) is 2, and the irrationality of a transcendental number (a number which is not algebraic) is 2 or greater. There exist numbers with infinite irrationality measure, called Liouville numbers.

Composite relatively prime numbers mean?

Relatively prime numbers share no common factors other than 1.

Why are rational irrational and real numbers not represented in tabular form?

Rational numbers are sometimes represented in tabular form, e.g. for proofs relating to different infinities.

Irrational and real numbers are not because there is no way to do it.

What is the proofe for this statement if even number is multiblied with odd number the result will be even number is even number?

Let p be even and q be odd. Since p is even, p = 2n for some natural number n. Then the product pq = 2nq, an even number.

What do you use a googol for?

it's a number it looks like this: 10^10^100 and googolplex is a number it is higher than the number of hydrogen atoms in the observable universe! scientist use googol for rocket science!

EDIT:

10^10^100 is a googolplex, not a googol.

A googol is 10^100 whereas a googolplex is 10^googol

Its use, however, has no mathematical significance. A googol was pretty much invented for fun by a mere 9-year old.
