Math Phobia or math anxiety is a very real problem that many young students and even adult professionals face.

**What actually is Math Phobia?** It is the doubt on one's mathematical abilities.

**How does it begin? **Many underlying reasons are there to fear and hate maths. It could be because of a substandard teacher at a young age. It could be because of parents' math anxiety which they subconsciously transferred in their child. The pressure of exams and tests, maths being taught as a right or wrong subject instead of a creative field of study are more reasons why Maths is the most feared subject in the world.

**How to get better and love maths? **Teachers and parents need to motivate and help students stay positive and enthusiastic about learning Math. One way is to give them open-ended problems to solve and discuss. If you realise the uses and applications of different fields of Maths in everyday lifestyle like percentages, estimations and fractions when shopping, measuring and fractions in cooking, decimals in financial transactions, trigonometry in flying plane and construction and so much more.

**DO maths to LEARN maths.** Solve as many mathematical problems, experiment on understanding, think before asking.

Keep going, keep learning.

Natural Numbers: The set of counting numbers is called **natural** numbers. It is denoted by N, where N = {1,2,3, …..}

Whole Numbers: when zero is included in the set of natural numbers, then it is a set of **whole** numbers. It is denoted by W, where W = {0,1,2, …..}

Integers: When in the set of whole numbers, natural numbers with the negative sign are included, then it becomes a set of **integers**. It is denoted by Z, where Z = {-…. , -2, -1, 0, 1, 2, …..}

Integers can be divided into negative and positive integers.

Prime Numbers: The natural numbers which have no factors other than 1 and itself are called prime numbers.

Co-prime Numbers: Two numbers that have no common factor except one are called co-prime numbers. Example: 11 and 18 etc.

Rational Numbers: The numbers that can be expressed in the form of p/q where p and q are integers and co-prime are called **rational** numbers. It is denoted by Q. Rationalnumbers can be positive or negative.

Irrational Numbers : The numbers which are not rational numbers, are called irrational numbers. or π = 3.141592 is an **irrational** number.

Real Numbers : Set of all rational numbers as well as irrational numbers are called real numbers. The square of all real numbers is positive.

Some important points on numbers :

- 2 is the only even prime number.
- Number 1 is neither divisible nor prime.
- Two consecutive odd prime numbers are called prime pair.
- All natural numbers are whole, rational, integer and real.
- Fractions are rational.
- 0 is neither negative(-) nor positive(+) number.
- Dividing any number by 0 gives infinity () whereas dividing 0 by any number gives 0.
- The sum and product of two rational numbers is always a rational number.
- The product and sum of a rational number and irrational number is always an irrational number.
- There can be infinite numer of rational and irrational numbers between two rational numbers and two irrational numbers.
