Suppose we want to solve
⎕ − 3 = 5
We have to find the missing number
In algebra,
We don’t write boxes
It has a variable − x
We write letters, like 𝑥
It has a variable − x
But, why write 𝑥? Why not boxes ?
- Writing x is easier to write than ⎕
- if there are two boxes, now do you tell which box is which ?
So let’s start ?
