Conditional Statement
A conditional statement is a mathematical concept of reasoning which is a very important skill that will help the students to analyze a given situation without any reference to a context or meaning. In other words, when an inquiry or statement is examined, the reasoning of said statement or inquiry is not based on the individual's opinion. Let us now see more about what is conditional statement.
What is conditional statement
In mathematics, a conditional statement is a logical statement with the form “if p then q”. Here, p is the hypothesis and q is the conclusion. In conditional statements, the statement is false only when p is true and q is false, otherwise the conditional statement is usually true. The related form of conditional statement is contrapositive, which means if not q then not p.
The conditional statement is symbolically written as:
p → q

How to write conditional statements?
We can follow the below mentioned steps to write a conditional statement.
Step 1: Look out for the condition that has the ‘if’ and ‘then’ part.
Step 2: The next step is to connect the condition with the consequence by using the ‘if… then…’ structure.
Step 3: Write a statement expressing logical relationship to connect the condition and consequence.
For example,
- True statements:
If the square of a number is even, then the number is even.
- False statements:
If a number is odd, then it is prime
What Are the Parts of a Conditional Statement?
To fully grasp conditional statements, students must understand their components. The parts of conditional statements are mentioned below:
- Hypothesis
- Conclusion
To understand the parts of the conditional statement, let us use an example
Conditional statement: If it is Friday today, then yesterday was Thursday.
Hypothesis: The hypothesis in the statement above is “if today is Friday.” The hypothesis always begins with “if.”
Conclusion: The conclusion in the same example is “then yesterday was Thursday.” Remember that the conclusion always starts with the word ‘then.’
The statement will be changed to either of the following if there is a change of order in the statement:
- Converse Statement
- Inverse Statement
- Contrapositive Statement
- Biconditional Statement
Common mistakes of Conditional Statements
When understanding the concept of conditional statements, students tend to make mistakes. Here, are some common mistakes and their solutions:
Mistake 1
Interchanging Hypothesis and Conclusion
Students must understand the distinction between hypothesis and conclusion.
Mistake 2
Confusing Necessary and Sufficient Conditions
In the equation, ‘if p then q,’ p is always sufficient for q. Restate the definitions of the statement when in doubt.
Mistake 3
Assuming that the Converse is True
Students should test the converse statement separately with examples and counterexamples. They should also make a note that the converse statement is not logically equivalent to the conditional statement.
Mistake 4
Ambiguous Language
Students must use precise and accurate mathematical language, and wherever possible they must use a symbolic notation to remove ambiguity.
Mistake 5
Not double-checking Logical Equivalence
Students must always use truth tables or logical reasoning to confirm that the statements are indeed equivalent to the original conditional statement

Real life applications of Conditional Statements
We use the concept of conditional statements in various fields and applications. Let us now see how conditional statements are used in real world applications.
Computer Science and Programming:
We use conditional statements in computer science and programming for if-else statements, which are used to control the flow of programs, we also use conditional statements to make decisions based on conditions in algorithms.
Mathematics and Logic:
We use conditional statements in mathematics and logic for, the proofs and theorems, where we use statements to prove conditional logic, it is also used in set theory, where conditional statements are used to find conditional relationships between subsets.
Engineering and Automation:
We use conditional statements in engineering and automation, where we use conditional statements to operate automated machines which operate based on conditional logic; we also use conditional statements for the functioning of traffic lights, which operate based on predefined conditions.
