Because otherwise different people will get different answers.For example,
2+3*5 will not equal 3*5+2
since the left hand side will be calculated as 5*5 = 25
and the right hand side as 15+2 = 17
Therefore, the commutative property will be lost and it will become virtually impossible to solve any but the simplest equations.
Replace each variables in the algebraic expression by its [known] value and calculate the value (ie evaluate) of the algebraic expression.
I think it is important because you need to know it when you get older.
meaning to evaluate the variable in an expression. An algebraic expression is also a problem that contains no equals sign and you don't solve it, rather you simplify it.It means to solve something.

you have to deduce the variable and evaluate the expression.

You have to substitute a value for the letter variable in the expression. This is what we call evaluating the algebraic expression. An example would be 3x+1=7, when x=2.
