There are a few numbers that do not need signs. You do not have to sign when timing something.

A mathematical expression has numbers and operation signs with no equal sign. Equations, on the other hand, do contain equal signs.
If there is an equal sign, it is called an equation; if there is a less-than, a less-than-or-equal, a greater-than, or a greater-than-or-equal sign, an inequality; if there is none of these, an expression.
9254+15892=25146
It depends which operation you are carrying out.
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.

This is a mathematical "expression".
A mathematical expression has numbers and operation signs with no equal sign. Equations, on the other hand, do contain equal signs.
Algebraic expression
One of them is equal to -27 and the other is equal to +13. They can be used together to produce other numbers, depending on what mathematical operation is used.
If there is an equal sign, it is called an equation; if there is a less-than, a less-than-or-equal, a greater-than, or a greater-than-or-equal sign, an inequality; if there is none of these, an expression.
an expression. or an inequality.
"3 and 5" is an example of a list of two numbers. If you want them combined or operated on in some way, then you need to say so. "And" is not a mathematical operation.

-- The only number equal to 84 is 84. -- The only number equal to 180 is 180. -- There's no number that can be equal to both 84 and 180. -- If you meant to talk about the result of a mathematical operation performed on 84 and 180, "and" is not a mathematical operation, so there's not enough information to do anything with.
That is called an expression.
