when a symbol such as <or> is placed between two expressions
An equation.
It's called an equation
Do you mean like this: (x + 5)(2x + 7) If so, then it means you multiply.
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.
Yes, an equation does involve a relation symbol. Specifically, it uses the equal sign "=" to indicate that the expressions on both sides have the same value. This symbol establishes a relationship between the two sides, showing that they are equivalent. Other relation symbols, like "≠" (not equal), "<" (less than), or ">" (greater than), are used in inequalities, not in standard equations.

its called an inequality

An equation
An equation consists of two expressions, one on either side of an equality symbol.

This is used in computer languages (including spreadsheets like Excel) to indicate inequality. If two numbers are not equal, then the first one is either larger or smaller than the second one. This symbol is sometimes used because the standard inequality symbol is not readily available.
