Writing a basic program - SS2 ICT Lesson Note

Write a basic program to compute algebraic equations

Here is a simple Python example that takes an algebraic equation as input and calculates the result for a given value of the variable:

python Copy code

# Define the algebraic equation as a function

def compute_equation(x):

    return 2*x**2 + 3*x - 5

# Get the value of the variable from the user

x_value = float(input("Enter the value of x: "))

# Calculate the result using the equation function

result = compute_equation(x_value)

# Print the result

print(f"The result of the equation for x = {x_value} is: {result}")

Explanation:

This Python code calculates and prints the result of an algebraic equation for a given input value of 'x' in a simple step-by-step manner:

1. The code defines an algebraic equation as a function called compute_equation(x) that takes one input parameter, 'x'. The equation used in this function is 2*x**2 + 3*x - 5.
2. It then asks the user to input a value for 'x' using the input() function, and it converts the input to a floating-point number using float(input("Enter the value of x: ")). This means you can enter a decimal number as 'x'.
3. Next, it calculates the result of the equation for the input value of 'x' by calling the compute_equation(x_value) function, where x_value is the user-provided value.
4. Finally, it prints the result using the print() function. The result is displayed as a formatted string that includes both the input value of 'x' and the computed result.

In summary, this code takes a value of 'x' from the user, plugs it into the equation 2*x**2 + 3*x - 5, calculates the result, and then prints out the result with the input 'x' value for the user to see

Remember that this is a basic program, and it assumes the user will input a valid numerical value for x. Just modify the compute_equation function accordingly.
