There is no agreed definition but the following, from the Encyclopedia Britannica is a good one. It defines mathematics asThe science of structure, order, and relation that has evolved from elemental practices of counting, measuring, and describing the shapes of objects.

If I understand it correctly, that means you should solve the following equation: (5 + 9 + 12 + x) / 4 = 9
We need to refer to the mathematical definition of the word "even." The most commonly accepted definition is that a number "a" is even if there exists an integer "n" which makes the following statement true: a = 2 x n -1 is an integer. So let n = -1 in the above equation and we get: -2= 2 x (-1) So -2 satisfies the mathematical definition for being even.
In my city, there are many ways to get from place to place: walk, ride the bus, ride a train, or drive a car.
An integer is odd if and only if it is not divisible by two.
No, it is not a definition: it is an imperative statement requiring you to do something!
How can the following definition be written correctly as a biconditional statement? An odd integer is an integer that is not divisible by two. (A+ answer) An integer is odd if and only if it is not divisible by two
the product of two integers is odd if and only if the two factors are odd
Which of the following is the best definition for the term dangling participle?
No, not always. It depends on if the original biconditional statement is true. For example take the following biconditional statement:x = 3 if and only if x2 = 9.From this biconditional statement we can extract two conditional statements (hence why it is called a bicondional statement):The Conditional Statement: If x = 3 then x2 = 9.This statement is true. However, the second statement we can extract is called the converse.The Converse: If x2=9 then x = 3.This statement is false, because x could also equal -3. Since this is false, it makes the entire original biconditional statement false.All it takes to prove that a statement is false is one counterexample.
A 150 degree angle is an obtuse angle because it is greater than 90 but less than 180 degrees
The statement is bi-conditional. The "if and only if" should have tipped you off immediately.
