It depends on the combination. Real numbers are closed with respect to arithmetical operations (+, -, *, /), as well as integer powers (exponents). So a combination of real numbers using any of these operators will yield a real number. But the set is not closed with respect to some fractional powers - for example, the square root of a negative number is not real.It depends on the combination.

The fundamental operations are operations in arithmetic: addition, subtraction, multiplication and division. These are the same whatever the base of the number system.

Numbers go on forever. Any number can be increased by adding 1, or by adding any other number, or by doubling that number, or by multiplying that number by any other positive number greater than 1. All such operations will result in a larger number, and you may perform such operations as many times as desired.

120 WRONG! That is the number of PERMUTATIONS. In the case of combinations, the order of the numbers does not matter, so there is only 1 5-number combination from 5 numbers.

Yes. When you add any whole numbers you get another whole number. That is what closed means in this context. The answer is still a whole number.

A collection of things together with operations on those numbers and the properties that the operations satisfy or in other words, a collection of numbers together with operations, properties of the operations, and a system of representing these numbers.

When people started classifying numbers in different ways Some numbers were grouped together and called Real numbers. Solutions that would create Imaginary numbers were simply explained away as impossible, later the rules for working with these numbers, but, even though they are not considered Real numbers some math operations will create Real number answers.

An expression which combines numbers and operations

There is no simple method. And it gets more difficult as you increase the number of permitted operations: powers, factorials and so on.

The fundamental operations are operations in arithmetic: addition, subtraction, multiplication and division. These are the same whatever the base of the number system.

How could you use inverse operations to divide larger number

Numbers are an abstract concept developed from simple counting of objects. The basic set of counting numbers has been expanded so that they include the set of integers, other rational numbers, irrational numbers, complex numbers and quaternions. Operations are the rules for manipulating numbers. The basic operations of arithmetic are addition, subtraction, multiplication and division.

Numbers go on forever. Any number can be increased by adding 1, or by adding any other number, or by doubling that number, or by multiplying that number by any other positive number greater than 1. All such operations will result in a larger number, and you may perform such operations as many times as desired.

The friendly number strategy is a way to complete difficult operations by dividing them into operations using friendly numbers, or numbers that are easy to work with. For example, you could use the friendly numbers strategy to solve 169 + 37 by breaking it down into 160 + 30 + 9 + 7.
