A conditional statement is a mathematical concept in reasoning. It is an important skill that helps students analyze situations objectively. 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.
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
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,
To fully grasp conditional statements, students must understand their components. The parts of conditional statements are mentioned below:
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: "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:
When understanding the concept of conditional statements, students tend to make mistakes. Here, are some common mistakes and their solutions:
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.
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.
In mathematics and logic, conditional statements are used in proofs, theorems, and set theory, where they are used for finding conditional relationships between subsets.
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. For example, if the light is red, then cars must stop; if it is green, then cars may go.
