Table Of 12

Introduction

The smallest composite number with exactly six divisors is 12, and its divisors are 1, 2, 3, 4, 6, and 12. Twelve is a composite number. The multiplication of 12 by various natural integers is shown in the table of 12. Greek mathematician Pythagoras is credited with discovering the table of 12.

Multiplication tables are of great use to solve problems of all levels. Not just basic algebraic sums but these tables can also be used to solve difficult problems such as calculus, Pythagoras' theorem, trigonometric equations, and more. In addition, knowing the multiplication tables will help you execute mental math rapidly, a skill that is essential for all competitive tests.

The Number: 12

The natural number 12 comes after 11 and before 13. Since the number 12 ends in a two, which is also an even number, it can be divided by two to get the result equal to 6. When we multiply 12 once, we get 12, when we multiply it twice, we get 24, and when we multiply it ten times, we get 120. In this way, we will get the mathematical table of 12. Due to the fact that 12 is a composite number, it has prime factors.

Significance Of Multiplication Table

The multiplication table helps solve various mathematics problems mentally and quickly. It is also applicable in several real-life situations.

For instance, if a candy costs INR 5, and we intend to buy 20 such candies, it will cost INR 100 in total. This can be determined in two different ways.

First is that we add the cost of one candy 20 times, i.e.

5+5+5+5+5+5+5+5+5+5+5+5+5+5+5+5+5+5+5+5 which is equal to 100.

Secondly, we can use the table of 20 and find what 20 times 5 equals. It gives 100.

Clearly, the second method is quicker and easier to use.

There are various other similar situations where tables can be really helpful.

Solved Problems

Example 1: Calculate (12 times 8) minus 15 using the 12 times table.

Solution:

We shall first calculate (12 times 8)-15 mathematically.

Using the 12 times table, we can calculate (12 times 8) less 15 as follows:

(12 times 8) - 15 =(12✕8)-15= 96 - 15 = 81.

So, (12 times 8) less 15 equals 81.

Example 2: Determine whether {(12 times 4) plus 10} equals 58 using the table of 12.

Solution:

Mathematically, we shall first write {(12 times 4) plus 10}.

Making use of the 12 times table: {(12 times 4) plus 10}=(12✕4)+10 = 48 + 10 = 58.

As a result, 58 is equal to {(12 multiplied by 4) + 10}.

Example 3: One litre of gas allows a car to travel 12 kilometres. Determine the distance that it will travel on 10 litres of gas using the table of 12.

Solution:

12 km is the distance a car can travel on one litre of gas.

As 12✕10=120

120 kilometres are travelled by car using 10 litres of gas.

Thus, 10 litres of gas will allow the car to travel 120 kilometres.

Example 4: Using a 12 times table, determine how many times a mourning dove will chirp in 8 hours if it chirps 12 times in one hour.

Solution:

12 chirps occur in an hour.

The number of chirps in 8 hours is, therefore, 12 times 8=12✕8= 96 from the table of 12.

It will chirp 96 times in 8 hours as a result.

Example 5: Determine (12 ✕ 9) - 32.

Solution:

Using the 12 times table as a guide, 12 times 9 = 12 ✕ 9 = 108.

(12 ✕ 9) - 32 = 108 - 32 = 76 .

Times Table Of 12

Times table basically represents that when a number n is added to itself ‘m’ times the result is equal to the number as “n ✖ m”, the repeated addition yields the same result as multiplication. It is shown below in the table.
