What is the no solution symbol?
Sometimes we use the symbol Ø to represent no solutions. That symbol means “empty set” which means that the set of all answers is empty. In other words, there is no answer.
Which are the real numbers?
Real numbers are the numbers which include both rational and irrational numbers. Rational numbers such as integers (-2, 0, 1), fractions(1/2, 2.5) and irrational numbers such as √3, π(22/7), etc., are all real numbers.
What is a real number diagram?
Below is a diagram of the real number system. Real numbers are mainly classified into rational and irrational numbers. Rational numbers include all integers and fractions. All negative integers and whole numbers make up the set of integers. Whole numbers comprise of all natural numbers and zero.
Is 12 a real number?
Reals: any number that is rational or irrational – any number on the number line. As you can see, −12 is an integer, but it is also a rational number because it can be made into a fraction: −121 and it is real because it can be found on the number line.
How can you tell a real number?
The Real Number Line is like a geometric line. A point is chosen on the line to be the “origin”. Points to the right are positive, and points to the left are negative….Any point on the line is a Real Number:
- The numbers could be whole (like 7)
- or rational (like 20/9)
- or irrational (like π)
Which number is the smallest?
0
Which is greatest number?
The greatest number formed is 95410. Ascending order 0 < 1 < 5 < 5 < 9. A number cannot begin with 0, so we will put it in the second place. The smallest digit (other than 0) is 1.
What is the greatest number between 1 and 10?

Why is 2 the lowest prime number?
A prime number is a whole number greater than 1 that can only be divided by itself and 1. The smallest prime numbers are 2, 3, 5, 7, 11, 13, 17, 19 and 23. The number 2 is the only even prime number. The number 7 has only two factors: 1 and itself.
What is Coprime number?
A Co-prime number is a set of numbers or integers which have only 1 as their common factor i.e. their highest common factor (HCF) will be 1. Co-prime numbers are also known as relatively prime or mutually prime numbers. It is important that there should be two numbers in order to form co-primes.
Are prime numbers even?
The only even prime number is 2. All other even numbers can be divided by 2. If the sum of a number’s digits is a multiple of 3, that number can be divided by 3. A composite number is defined as any number, greater than 1, that is not prime.
