In many ways. It really depends on the algebraic expression. If several terms are added/subtracted, you can usually combine similar terms (terms that have the same combination of variables). If variables are multiplied, you can combine the same variable, adding the corresponding exponents. Sometimes expressions get simpler if you factor them; sometimes you have to multiply out (in other words, the opposite of factoring). Quite frequently, you have to use a combination of methods to simplify expressions. Take an algebra book, and look at some of the examples.

PEMDAS is an acronym of the order in which operations must be carried out: Parentheses, Exponents, Multiplication, Divisin, Addition and Subtraction. You cannot use PEMDAS to multiply, since it is not an operation. give an example.

You multiply 5x5 then 9x1.

No.
use disributive property
An example of how to use the distributive property: If you have 6x(5+4) you multiply 6x by 5 and get 30x. Then you multiply 6x by 4 and get 24x and then you would have 30x+24x which = 54x

When you add or multiply, you can group the numbers together in any combination.
