3=3

..-(P-1)
4

Please don't abuse the resources by posting a million different problems. Evaluate previous solutions and attempt to reapply them. Or at least attempt to be less obnoxious by posting the problems in one post. IN LEFT TO RIGHT FORMAT.

Actually, posting 5-10 problems in a single post is a good way to get ignored or flamed for homework dumping.

The best way is to post a problem, indicating where the difficulty lies. After a solution has been given, try to work similar problems on your own, and show your answers for verification, or your work for further help.

It seems like you have provided an equation and an expression. Let's break down each one and explain them step by step.

1. Equation: 3 = 3
This equation states that the number 3 is equal to the number 3. Here, both sides of the equation are the same, so we can say that this equation is true. It is important to note that equations are expressions that have an equal sign (=) between two sides.

2. Expression: ..-(P-1)
This expression involves the variable P. Without knowing the value of P, we can still simplify the expression by following the order of operations (also known as PEMDAS/BODMAS). Let's break it down:

a. Inside the parentheses: P - 1
Here, we subtract 1 from the variable P. If you have the value of P, you can substitute it and evaluate the expression further.

b. Subtract the result from Step (a) from dot-dot (..).
Unfortunately, without further information, it is not possible to determine the exact result of this expression.

3. Number: 4
This is a standalone number and doesn't require any further explanation. It is simply the value 4.
