Fangcheng (mathematics)
Okay kiddo, so fangcheng is a big word that means "algebra" in Chinese. Algebra is a type of math where we use letters and symbols to represent numbers and figure out how they relate to each other.
So, imagine you have a toy car and you want to figure out how fast it can go. We could use fangcheng to represent this. Let's say we use the letter "x" to represent the speed of the car. Now we can use fangcheng to figure out how fast the toy car goes when we push it.
We can write an equation that looks like this:
x + 5 = 10
This means that the toy car's speed (represented by "x") plus 5 (because we're pushing it) equals 10 (how fast it ends up going).
Using fangcheng, we can solve for "x" (the speed of the car) by subtracting 5 from both sides of the equation:
x = 5
So, the toy car goes 5 units of speed when we push it.
That's just one example of how fangcheng (algebra) can help us figure things out in math. We can use it for all sorts of different problems, like figuring out how much money we'll have after buying a toy or how many apples we need to make a pie. Hope that helps!
