Why is it important to have rules for simplifying an expression that contains more than one operation?

Because if you didn't, there could be more than answer and there would be no way to decide which is correct.
For example, "10+6/2": If you do this from left to right, you get 16/2 = 8. If you follow the rules, you do the division before the addition: 10+3 = 13.
13 is correct.
If you wanted 8, you would write (10+6)/2, then you would have to simplify inside the parentheses before dividing.

What is an expression that contains a variable a number and at least one operation?
That looks like the description of an EXPRESSION. However, an expression need not have "at least one operation"; a single number, or variable, is a perfectly valid expression.
What is the solution of this problem in math- simplifying each expression- -8-10x-2?
The question contains an expression -10-10x = -10(1+x). Since it is not an equation nor inequality, it cannot have a solution.
