First, in one of our previous articles about what makes 2021 different from 2020. We generally talked about situations and conditions surrounding us since the spread of something new in 2020 with a better hope in 2021. We also learned that humans are not perfect

and go through our whole lives making mistakes for a better purpose. Even a wise man has to apologize sometimes. This time the article will focus more on the groups of several 2021 itself as not just a literal number. We may not learn this directly while at school, but we may learn about this progress at the learning place. Our foundation must be strong on learning at the learning place and pace. If humans learn the uniqueness of 2021, they will consider exposing their hidden potential. This article shares the unique idea of the number 2021, which many of us may not see before. Humans will develop more insight and learn in some of the progress of getting by. It would be better to share the hidden uniqueness of the number 2021.

The simplest reason for 2021 in which the unique form group of numbers. 2021, we know the concatenation of two consecutive integers, 20 and 21. That could result in 2021, not only meaning to keep continuous for the activity to improve. 2021 as in fact, has a sum of 5. As we can see, if we add those numbers from 2 with 0 with 2 and with 1, we will get 5. We as humans assume about 5 is one set of fingers in one palm so that we can do our full work. Also, the number 2021 is based on representations, like the other ways of writing it, in the Roman numeral as MMXXI, which is also the sum of 5, or in the written binary as 11111100101, which also indicates the consecutive integers.

Another reason for the number 2021 is a unique number from their two consecutive integers and their sum. This number is composed of two prime numbers. 2021 factorization is 43 and 47, bringing us about the divisor of 2021 except their number. The numbers 43 and 47 are also evidence of two consecutive prime numbers, as number 43 is the 14th prime number and number 47 is the 15th prime number. In which philosophically thinking, we as humans need to be sure to keep moving on in our uniqueness to be equal with those surrounding us. It is worth having ourselves keep moving to a better reach in our uniqueness to become non-unique, as the natural numbers have shown us.

On the other hand, another fact of the number 2021 is deficient based on many viewers. This because the sum of its proper divisor without the number itself is equal to 91 from the summation of 1, 43, and 47, in which it is has a deficiency equal to 1930. Unlikely the sum of two prime numbers in the 2021 divisor is equal to 90, which has a deficiency equal to 1931. That indicated that it is worth becoming different and having a deficiency in life with a better chance.

Finally, the uniqueness of group number 2021 is not just the same perspective in most human points of view perspective based on their basic idea. Mathematicians and Philosopher value their groups of numbers of 2021 should be coming from the actual numbers from 0 to 10 and vice versa with their brackets and basic arithmetical operations, as many of us have tried out. Now, we will see how groups of 2021 got form out of it like if we line up the basic number from 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, with their basic operations from + – / *, and brackets { [ ( ) ] } in our convenient, then we Mathematician believe this fundamental math operation can be brought to any number in any form, but in this case. Mathematician believes it also with a proper operation. Then it can form a value equal to 2021 as well, as we will see some of the examples that several passionate mathematicians have done. I cannot mention all of their names but allow me to thank you for sharing your work. Therefore, the way to approach the value of 2021 based on those actual numbers and operations are like:

01) By ignoring the BEDMAS rules, then we can get: 10-9*8*7*6+5-4*3*2-1 = 2021

02) By medium using the BEDMAS rules, we can have:

10*(9-8+7*6*5-4-3-2)+1 = 2021

10*(-9+8+7*6+5*4*3)*2+1 = 2021

10 x (-9 + 8 + 7 x 6 + 5 x 4 x 3) x 2 + 1 = 2021

03) By strictly using the BEDMAS rules, we have:

{(-10-9+8*7+6)*[(5*4+3)*2+1]} = 2021

{[(10+9)*8*(7+6)]+[5*(4+3*2-1)]} = 2021

{[(10+9)*(8+7/6)-5]*4-3}*(2+1) = 2021

04) By uniquely using the BEDMAS rules, we have:

{10+[(9+8+7+6)*(5+4^3-2)]+1} = 2021

{1+2*[3^4*(5+6)+7*(8+9)]} = 2021

From those 4 forms as we know, 2021 has 4 divisors like 1, 43, 47, and 2021, also represented by human languages with 4 letters like twenty thousand twenty-one. In the other idea, it philosophically means that if we ignore rules, like the BEDMAS (Bracket Exponent Division Multiplication Addition Subtraction), then we have a very limited option in our life to live. If we follow the rules half-handedly, we may have more options. However, indeed those options are similar with different progress. Now, if we follow the rules themselves like we follow our life to live rules, then we will not only have peace, joy, and love, but also we can always have more and more options to choose from in our lives to live. Lastly, being unique does not mean we must break life’s rules to live. Being unique with tons of options will be brought us to be accepted by the community as long as we can follow the rules of life to lives. Because being common or different in our life does not mean we need to break the rules of life to live limitless to infinity.

If some of us have wondered whether the sum of 2021 is 5, why do we go with the form of 4? Should not it be 5? Then the next one is the last one about the beginning of 2021. Will be share with you what the 5th form will be about?
