Numbers from 1 to 9: Uses, List, Number Puzzle, Problems

All the Numbers consist of digits from \(1\) to \(9,\) including \(0.\) Numbers are in the form of language shared by all mankind, doesn’t matter if they are from India or the USA, male or female, Hindu or Muslim. It is used for counting money, calculating the distance between two places, time, date, year, and weather.

We use numbers in school and work, counting money, measurements, phone numbers, password on our phones, locks, reading, page numbers, etc. Therefore it is an essential concept that has to be learnt at a very young age. It is essential for students to be thorough with this topic. Continue reading to know more.

What are Numbers?

Numbers have a very important role in mathematics as well as in real life. A number is used to count, measure and label.

Example: \(1, 7, -5\) etc.

What is Number System?

The method of expressing numbers by writing a mathematical notation for representing the numbers of a given set by using the numbers or symbols in a consistent manner is called number system.

Integers

All numbers that is not fraction or that do not have the decimal place in them are known as integers. 

\(Z{\rm{ }} = {\rm{ }}\left\{ { – \infty \ldots \ldots . – 3,{\rm{ }} – 2,{\rm{ }} – 1,{\rm{ }}0,{\rm{ }}1,{\rm{ }}2,\;3 \ldots \ldots \ldots + \infty } \right\}.\) Positive Integers \((1, 2, 3, 4…)\) are the set of all positive integers, negative Integers \((-1, -2, -3…)\) are the set of all the negative integers. \(0\) is neither the positive nor the negative integer.

Natural Numbers

Starting from our childhood, we are using numbers like \(1, 2, 3, 3, 4, …\) to count and calculate.  When counting objects in a group, we start with \(1\) and then \(2, 3, 4, 5,\) and so on. Counting objects in this manner is a normal process. As a result, \(1,2,3,4,….\) are known as natural numbers. 

However, fractional numbers like \(\frac{6}{{11}},\frac{{17}}{4},\frac{{123}}{{5048}}\) and decimal numbers like \(8.24, 33.08, 6175.560\) are not natural numbers.

By adding \(1\) to any natural number, we get the next natural number. There is no existence of greatest or last natural number. So, the first natural number is \(1,\) and there is no last or greatest natural number.

Whole Numbers

The natural numbers, along with the number zero \(0\) form the collection of whole numbers. That is \(0, 1, 2, 3, …\) are called the whole numbers.

Thus, a whole number is either zero or a natural number.

Even Numbers

A number that is exactly divisible by the number 2, is called an even number. For example: \(34, 68, 104,\) etc. Even numbers end with the digits \(0, 2, 4, 6\) or \(8\) always.

Odd Numbers

A number that is not exactly divisible by the number \(2,\) is called an odd number. For example: \(31, 79, 157,\) etc. All the odd numbers end with the digits \(1, 3, 5, 7\) or \(9.\)

Roman Numerals

The numerals \(0, 1, 2, 3, 4, ….9\) are used in writing different numbers. These numerals are of Indian origin, and they were adopted by the Arabs and spread across Europe. As a result, the system is known as Hindu-Arabic numerals. One of the early systems of numeration that is still in common use today was developed by Romans and is known as the Roman numeral system. We use the Roman numerals in different places like the numbering of different volumes or parts of books, numbers of chapters, numbers of issues of magazines, numbers on clock faces etc.

Example: \({\rm{I,}}\,{\rm{II,}}\,{\rm{III, }}….\)

List of Numbers from 1 to 100

The list of numbers from \(1\) to \(100\) is given below,

1 to 9 Numbers Puzzle

In number puzzle, the numbers from \(1\) to \(9\) must be placed into a grid of cells so that each row or column contains only one of each number. 

Let us see some examples of number puzzles.

Q.1. Solve the below the magic triangle

Ans: Arrange the numbers from \(1\) to \(9\) along the sides of the triangle.
Use each number only once.
Place the numbers so that there are \(4\) numbers along each side of the triangle.
Arrange the numbers so that the sum of the numbers along each side is \(17.\)
Thus,
\(1+9+5+2=17\)
\(1+6+7+3=17\)
\(2+8+4+3=17\)

Hence, the answer figure is given above.

Q.2. Find the missing number.

Ans: Read the first two rows of numbers horizontally, each as one number i.e. \(289\) and \(324.\)
The pattern is that \(17×17=289\) and \(18×18=324.\)
So it stands to reason that the bottom row will be \(19×19=361\)
Thus,

Hence, the missing number is \(1.\)

Solved Examples- Numbers from 1 to 9
