"Or" in life usually refers to the selection relationship between two or more things, which means that one or more conditions can be established. For example, I can ask you to do your homework or clean the room, and only need to complete one of the tasks.

"Or" in mathematics is a logical conjunction, which is usually used to construct compound propositions. In mathematics, "or" means that at least one of two or more propositions is true. When two propositions are connected by "or", as long as one of them holds, the whole compound proposition holds. For example, in the proposition "2+2 = 4 or 1+ 1 = 3", one proposition is true, that is, "2+2 = 4", so the whole compound proposition is true.

To sum up, the "or" in life represents the choice relationship, and the "or" in mathematics represents the logical relationship. In life, we can usually choose one or more of these options; In mathematics, "or" means that at least one condition is true. This is the difference between "or" in life and "or" in mathematics.
