SIMPLE AND COMPOUND STATEMENTS
Mathematical logic can be defined as the study of the relationship between certain objects such as numbers, functions, geometric figures etc. Statements are verbal or written declarations or assertions. The fundamental (i.e logical) property of a statement is that it is either true or false but not both. So logical statements are statements that are either reasonably true or false but not both.
Example: The following are logical statements:
(1) Nigeria is in Africa
(2) The river Niger is in Enugu
(3) 2 + 5 = 3
(4) 3 < 7
| P | Q | P˄Q |
|---|---|---|
| T | T | T |
| T | F | F |
| F | F | F |
N.B The educator should ask the students to give their examples
Example: The following are not logical statements because they are neither true nor false.
