# Introduction to the new decade 2020 !

To start a new year with the love for math and science, I made a funny solving of a "Today's" problem. Disliking it counts as a like to me :P . For the introduction of the new year:

## You can skip this note if you are not into jokes.

The following steps explain the solving process of the problem (1 Jan 2020) [it is about the no. 2020 we ae doing math with]:

We want to express 2020 in the form of $a^{2} -b^{2}$ :

• $2020 = a^{2} -b^{2} = (a+b) \times (a-b)$
• Since these are powers, we can use the $Yeet.theorem$ to yeet over the exponent: $2020 = 2 \times a -2 \times b$
• $1010 = (a - b)$
• We repalce $(a-b)$ with 1010 at eq.1 which we get:
• $2020 = (a+b) \times (1010)$
• $2 = (a+b)$ divide both sides by 1010

We have the given system to solve: $\begin{cases} 2 = (a+b) \\ 1010 = (a - b) \end{cases}$/extract_itex] • $1012 = (a + b) + (a - b)$ • $1012 = 2 \times a$ • $506 = a$ Finding $b$: • $1010 = (506 - b)$ • $b = - 504$ But we cannot have negative numbers so $b = 504$. We have solution that $\boxed{2020 = 506^{2} -504^{2}}$ Note by Nikolas Кraj 11 months ago This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science. When posting on Brilliant: • Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused . • Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone. • Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge. • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

It is a joke; a meme, that represents a 'proof' of a theorem:

It was just a pun. But thank you anyway.

This is misuse of the Yeet Theorem. The Yeet theorem states that you can yeet the exponents to the end of the equation.

Just saying, this is a joke, I'm not trying to be mean in any way.
