    I have found that as you progress the levels we call math, if you practice and get ahead on your own it becomes easy. Treat it as a game.

    Math is important because we use it everyday in our lives. You don't have to be an astrophysicist or a mathematician to understand the full impact of math. You apply it everyday when buying things, when cooking, when planning out your schedule for the day. It surrounds us everywhere, provides the foundation of analytical thinking, and lies behind the inventions of humanity.

  my punny brain is still like 0/0=0 1/0=0 because there no way for 1/0 to turn into any number and zero means nothing and 1/0 would be nothing due to the denominator being 0 since 1 divided by 0 would be 0
  same with 0/0

    You can have a whole pizza, or you can divide a pizza into 2 parts, 3 parts, 4 parts, or as many as you want (but too many would be not much pizza). How can you divide a pizza into 0 parts?

  When assuming x is not equal to 0, x/0=k ; x/0 times 0 = k times 0; how do you come up with x on the left side of the equation when x times 0 = 0. Why would the end not be 0=0?

  What if I programmed a calculator by code and don't have any exceptions like 0/0.
  

   cout << x/y << endl; 

  
  And if I enter x = 0 and y = 0, what would the program do? Will it crash?

    The result of division by zero depends on the language. In JavaScript, the result is NaN (not a number), in Python, a ZeroDivisionError exception is raised, in Rust, the code will not compile, and in C++, the output is "Floating point exception".

    As you can see, each language has its own way of handling division by zero. T

  What if in an expression, you don't have any knowledge of a variable in that expression. Such as "2x + 5". How would you solve for x?

    Until the value of x is given, the expression would remain unsolved and as the most simplified form, "2x + 5".
