They are expressions.
Yes. It is equal to zero. Yes, mathematical expressions can contain numbers, variables, and mathematical operations but do not contain an equal sign or inequality sign.
All expressions DO contain equals signs.
That is called an inequality.
inequality sign
Yes, when the inequality has a less that or equal to sign, or a greater than sign or equal to sign, then the equal sign can be replaced and get a solution that is common to both the equation and the inequality. There can also be other solutions to the inequality, where as the solution for the equation will be a valid one.

An inequality must have a greater than sign (>) OR a less than sign (<) OR a greater than or equal to sign (≥) OR a less than or equal to sign (≤).
With the equal sign (=).
An inequality is similar to an equation, in that it compares two expressions. But in an equality, instead of an equal sign, you would usually use one out of the following inequality symbols:* less than * less than or equal * greater than * greater than or equal
The sign is "greater than or equal to" or ≥
If the "comparison symbol" is the equal sign, it is called an "equation". If the symbol is less than, greater than, less-than-or-equal, or greater-than-or-equal, it's called an "inequality".
No, expressions do not have equal signs. Equations do, though. You can think of it like this: Equtions have EQUAl signs, while expressions do not.No, an expression cannot have an equal sign. If it were to have an equal sign, it would then be an equation.
Any inequality will work - for example, 5 is greater than 3 (5 > 3).
