Is "or and" equivalent to "and or"? [closed]

In common English, we can use the phrase "and or" to indicate that any of the following cases can apply, e.g. "I can have a strawberry and or a banana", meaning I can have either the strawberry, the banana, or both.

Now suppose I swapped the wording from "and or" to "or and". Does this phrase have the same meaning? Is the phrasing commutative such that "or and" is equivalent to "and or"?

The "and or" structure you describe is not universally recognized or accepted as correct. When it is used, it's normal to include a forward slash, "an apple and/or a banana". But I would never use this in formal writing, except in mathematical writing. "Or/and" is going to convey the same meaning, but is less common.

The formally correct way would be "an apple, a banana, or both".
