3. The number of rows and columns in a matrix.
5. Refers to the property that the subject of the statement can have.
7. A statement that is either true or false, but not both.
9. It is the process of creating proposition from a propositional function.
15. A formula which has both some true and some false values for every value of its propositional variables.
17. This law states that when three real numbers are added or multiplied together, then the grouping of the numbers does not matter.
19. The smallest set that contains all elements of a given set.
20. A collection of objects or numbers, typically denoted with curly braces.
23. A logical conditional statement in which the antecedent and consequent are interchangeable.
24. A set of all elements that are members of two sets.
25. This law states that when we add or multiply two values, then the change in order of the values, does not change the result.
27. The subset of a set that contains no elements.
28. The process of forming the opposite of a given statement or proposition.
29. A set of numbers arranged in rows and columns so as to form a rectangular array.

1. An arrangement of objects in a specific order.
2. A law property in mathematics where applying an operation multiple times yields the same result as applying it once.
4. A logical operation that connects two statements with "or" and is true if at least one of the statements is true.
6. A science of a study to evaluate an argument.
8. A formula which is always false for every value of its propositional variables.
10. A logical operation that combines two statements.
11. A sequence of propositions.
12. A logical operation that returns true only if both operands are true.
13. A quantifier that expresses "for all elements" in a set.
14. A compound statement formed by joining two statements with "and".
16. The rule used to count the number of combinations where order doesn’t matter.
18. A set that contains no elements.
21. A formula which is always true for every value of its propositional variables.
22. A matrix with the same elements as its transpose.
26. A law property that states that any proposition (or set) combined with its respective identity element (or empty set) remains unchanged.
