| Problem | What sets of numbers does belong to? | |
| Answer | belongs to these sets of numbers: Irrational numbers Real numbers | The number is irrational because it can’t be written as a ratio of two integers. Square roots that aren’t perfect squares are always irrational. |
What is a number set in math?
A combination of a real and an imaginary number in the form a + bi, where a and b are real, and i is imaginary. The values a and b can be zero, so the set of real numbers and the set of imaginary numbers are subsets of the set of complex numbers. Examples: 1 + i, 2 – 6i, -5.2i, 4. Read More ->

What are odd numbers from 1 to 1000?
There are 500 odd numbers from 1 to 1000.
How do you find the number of combinations in a set?
Remember, the formula to calculate combinations is nCr = n! / r! * (n – r)!, where n represents the number of items, and r represents the number of items being chosen at a time.
The set of whole numbers is exactly the same except that we include 0 in the set. Subtraction reveals negative numbers, which leads us naturally to the set of integers, So the integers are the whole numbers plus the negative (whole) numbers. The next operations we learn are multiplication and division.
In which list are the numbers arranged from greatest to least?
ascending order
If the numbers are arranged from the least to the greatest, then it is called ascending order. In this form, the numbers are in increasing order. The first number should be lesser than the second number. If the numbers are arranged from the greatest to the least, then it is called descending order.
