What is the definition of a mathematical sentence?
Basically, a sentence is a formula which is either true or false, e.g. 1 < 2 (it is true of course), 0 = 1 (this is false, but still a sentence). [We'll assume we are working with real numbers....] If you have variables, they must be "quantified", that is, you either say that the formula holds for every value of the variable, or for some (possibly unknown) value of the variable. 1) 1+2 = 3 2) x+2 = 3 3) x+2 = 3, for some x 4) x+2 = 3, for every x 1 is a true sentence, 2 is not a sentence, 3 is a true sentence (since x=1 is a solution), 4 is a false sentence (because x=0 is an example for which the formula is false). A mathematical sentence in algebra is also known as an expression. An expression can be defined as a sentence that has a number, an operation, and a letter in it. When a mathematical sentence is not in algebraic form, it just has to have two numbers and an operation.
A solution set is all the numbers that make a mathematical sentence is called a what?
A solution set makes a mathematical sentence TRUE.
What is the difference between a mathematical sentence and a mathematical statement?
Well, honey, a mathematical sentence is like a simple equation or inequality, while a mathematical statement is a broader declaration that can be true or false. So basically, a sentence is just a small piece of the puzzle, while a statement is the whole shebang. Just remember, in math, it's all about precision and not getting your variables in a twist.
The value for a variable that results in a true sentence is called an?
a "solution"
What are the truth value of the sentence P v P?
True

Is the following sentence true or false an ecological model may consist of a mathematical?
True
Is the following sentence true or false An ecological model may consist of a mathematical formula?
True
What value for x could make the sentence true?
It depends on the sentence.
Is x equals 0 a mathematical sentence?
What do you mean by a "mathematical sentence"? In some practice in analysis (Calculus stuff), we call a statement a sentence if it looks like one or any combination of the following: "For all a in set A, condition P(a) is true/false" "There exist some (or unique) a in set A where P(a) is true/false" So in that practice, your statement is NOT a sentence, but if you phrase it "There exist a unique x in our set where x = 0 is true" or simply "There exist a unique element x where x = 0" It would be a sentence. BUT, I am pretty sure what I am talking about is not the same "mathematical sentence" as yours.

What is a statement in discrete mathematics?
A sentence formed using words and mathematical symbols which is either true or false but not both.
An equation that is true for every value?
identity
What value of x makes this sentence true?
Unfortunately the sentence is missing to be able to get the value of x.
The value for a variable that results in a true sentence?
That's the "solution" to the equation described by the sentence.
