Table of 72

Introduction

Table of 72 is the multiplication table obtained by multiplying whole numbers individually to the well-known number 72.

72 is one of the easiest and most comfortable numbers because it is even and ends with two. Other even numbers that end with the highest even number like eight have a little complication in multiplication and addition. This is the same as well as for the highest odd numbers. But we are going to simply deal with a trouble-free and smooth number known as 72.

Generally, 72 is an even number below 100 and above 50. In this segment we are

going to cheer up with the multiplications of 72 as well as its addition

Detailed explanation

As we all know 72 is one of the product tables in mathematics. But we are on the track to getting the easiest and most delicate ways to solve mathematical equations, solving numerous MCQ-based questions and so on.

Table 72 is obtained by multiplying 72 with the whole numbers subsequently.

In other ways, it is also described as adding seventy-two repeatedly to get the product of any whole number. Let us look into an instant example to make things better,

\begin{equation}

72 \times 3=216

\end{equation}

This can also be obtained by adding 3 seventy-two subsequently to get the consequent number.

72+72+72= 216

This will be followed for all other whole numbers to get the final product. But adding 72 for 2 times is looking good but resuming it up to 20 or 30 times makes it much more difficult to get the result than the actual problem does. So the mathematicians in the primitive period found an interesting and easiest way for doing that so. That is the multiplication of numbers. They discovered that repeatedly continuing addition is the same as multiplying the specific number with the number of additions that took place. As a result, widely-known tables originated.

Multiplication Table of 72

The times table basically represents that when a number is added to itself the number of times equal to the number we intend to multiply it to, the repeated addition yields the same result as multiplication. It is shown below in the table.

Significance

• From learning such tables, we can solve a problem efficiently and quickly.

• Performing this kind of multiplication repeatedly helps increase our problem-solving skills and the presence of mind is more stable among children, thus increasing brain power.

• With the help of the table, mathematicians solved more complicated equations that literally lead to technological developments.

Solved examples
