That's called an "operator", for example, the plus sign in 3 + 4. The numbers are the "operands" - that is, the numbers (or expressions) operated upon. More precisely, a binary operator, since it works with two operands. In theory, an operand is just a special way of writing a function, since a third number is calculated, according to certain rules, from the other two.

What are expressions that have the same value no matter what x represents called?
algebraic expressions
A mathematical statement that two expressions are equivalent?
When two expressions are equal then it is an equation. This is indicated by putting an equals sign between them.So, for example, all of the following are equations:2 = 22 + 3 = 52x + 3 = 4y - 7For comparison, if the statement contains a less-than or greater-than symbol, it is an inequality, even if it also has an equals sign. Here are some examples:2 + 3 < 72x >= 3y
What mathematical symbol would you need to place between 2 and 3 so that the result is a number between 2 and 3?
It is a desimol (2.3)...
What mathematical symbol can you put between 1 and 2 to make a number greater than 1 but less than 2?
the square root symbol. that would make it 1,/2 (i don't know how to make a square root symbol, sorry) but since the numbers are next to each other it is assumed that they are being multiplied and the square root of 2 is approximately 1.414 right in between 1 and 2 :)
