Let's look at the Math: 9+10 = 21

Mathematics is a subject that is precise and relies on logical reasoning. It follows certain rules and principles that allow us to solve problems and find solutions. However, there are instances where people come across equations that seem to defy the basic principles of mathematics. One such example is the equation “9+10=21,” which gained immense popularity on the internet and social media platforms.

It all started with a short Vine video, in which a young boy is asked what is 9 plus 10. He confidently responds, “21.” The video quickly became viral, and people started sharing it across various social media platforms. It became a sensation, attracting millions of views and countless comments.

The video, although amusing, sparked debates and confusion regarding the basic principles of addition. Some people questioned if there was an alternative approach to mathematics that would make the equation “9+10=21” correct. Others believed it to be a mere joke and a way to entertain people. So, let’s look at the math behind this peculiar equation.

In traditional mathematics, the sum of 9 and 10 is 19. The basic addition principle states that when two numbers, in this case, 9 and 10, are added together, their sum is obtained by combining the total value of both numbers. Hence, it is indisputably 19.

However, some individuals tried to perceive the equation differently. They argued that, by grouping the numbers differently or using alternative numerical systems, it might be possible to reach the answer of 21.

One example of such an alternative approach could be the base-12 numerical system. In this system, numbers are grouped in sets of 12. Following this logic, when we consider “9+10” in base-12, we can add by counting from 1 to 9, then from 10 to 21. Therefore, in base-12, “9+10” indeed equals 21.

While this alternative explanation seems plausible, it is important to note that the video and subsequent discussions were more about creating amusement and entertainment rather than proposing a new mathematical theory. It is mostly a humorous way to challenge the basic principles we learn in mathematics and generate a playful debate among the viewers.

In conclusion, the equation “9+10=21,” which gained immense popularity on the internet and social media platforms, is not mathematically correct in the traditional sense. In the base-10 numerical system that we commonly use, the sum of 9 and 10 is 19. However, some individuals attempted to present alternative approaches by considering different numerical systems, such as base-12, where “9+10” does equal 21. Nevertheless, it is crucial to understand that the equation was intended to be a joke and not a serious challenge to mathematical principles. It serves as a reminder that sometimes humor can give us a fresh perspective on things and invite us to think outside the box.
