One learning experience that I learnt this week is ( Algebra )
in algebra we learnt about a variable. A variable is something that is used to represents a letter, shape And a symbol that can change.
Example -
15 + t = 20 t= 5
15 + y = 40 y = 25
The number behind the symbol can change such as
2 + h = 7
4 - a = 2
