PROBLEM OVERVIEW

What this Python exercise asks you to practise

This scenario tests add two integers. It belongs to the Python Foundations roadmap and uses the integers · arithmetic pattern.

Programs, values, variables, input(), print(), and basic type conversion.

INPUT FORMAT

Program input

Two integers, one per line.

VERIFIED SAMPLE CASES

Input and expected output

Normal case

A shop combines quantities from two small orders.

Sample input

12
8

Expected output

Why: split() separates the two tokens, map(int, ...) converts them, and + adds them.

Boundary or variation

A ledger combines a credit and a negative correction.

Sample input

25
-9

Expected output

Why: split() separates the two tokens, map(int, ...) converts them, and + adds them.

PYTHON SOLUTION

Reference answer with explanation

first = int(input())
second = int(input())
print(first + second)

Read one number per line, convert each text value with int(), then add the two numbers.

Common beginner check: Forgetting that input() returns text, even when the user types a number.
