**Transcription for Educational Website on RSA Algorithm:**

Calculate the following variables using the RSA algorithm:

Given:
- \( P = 3 \)
- \( q = 5 \)

Tasks:
a. Calculate \( N \)  
b. Calculate \( \varphi(N) \)  
c. Calculate \( e \)  
d. Calculate \( D \)  

**Explanation:**

- **N** is the product of the two primes \( P \) and \( q \).
- **\(\varphi(N)\)** is the Euler's totient function for \( N \), which is calculated as \( (P-1) \times (q-1) \).
- **\(e\)** is the public exponent chosen such that \( 1 < e < \varphi(N) \) and \( e \) is coprime to \(\varphi(N)\).
- **\(D\)** is the modular multiplicative inverse of \( e \) with respect to \(\varphi(N)\), satisfying the equation \( e \times D \equiv 1 \, (\text{mod} \, \varphi(N)) \).

This calculation is a fundamental part of understanding how public and private keys are generated in RSA encryption.
