ELI5: Explain Like I'm 5

Flexible algebra

Well hello there! Do you like solving puzzles? How about numbers? If yes, then you'll love flexible algebra!

Do you know what algebra is? It's like solving puzzles with letters instead of numbers. These letters are the missing pieces that we have to find out.

Now, in flexible algebra, we have these missing pieces not only in numbers but also in symbols. You know what symbols are, right? They're like +, -, x, and ÷ that we use to solve math problems.

So flexible algebra is like solving puzzles where we have to find out not only what the missing numbers are, but also what the missing symbols are.

Let me give you an example.

2 ? 4 ? 5 = 30

Now, we have to find out what the missing symbols are. We know that the missing numbers are between 1 to 9.

So let's start solving it.

First, we have to find out what the missing symbol between 2 and 4 is.

We know that when we add 2 and 4, we get 6. So, the only missing symbol that can give us 6 when we add 2 and 4 is +.

So let's replace the first missing symbol with +.

2 + 4 ? 5 = 30

Now, we have to find out what the missing symbol between 4 and 5 is.

We know that when we multiply 4 and 5, we get 20. So, the only missing symbol that can give us 20 when we multiply 4 and 5 is x.

So let's replace the second missing symbol with x.

2 + 4 x 5 = 30

Now, we have to solve the equation.

We know that we have to solve the multiplication first. So, 4 x 5 = 20.

2 + 20 = 22

So, the missing number in the equation is 22.

So, that's how we solve puzzles in flexible algebra. We not only have to find out the missing numbers, but also the missing symbols.
