+## 기능 요구사항
+입력한 문자열에서 숫자를 추출하여 더하는 계산기를 구현한다.
+
+쉼표(,) 또는 콜론(:)을 구분자로 가지는 문자열을 전달하는 경우 구분자를 기준으로 분리한 각 숫자의 합을 반환한다. <br>
+예: "" => 0, "1,2" => 3, "1,2,3" => 6, "1,2:3" => 6 <br>
+앞의 기본 구분자(쉼표, 콜론) 외에 커스텀 구분자를 지정할 수 있다. <br>
+커스텀 구분자는 문자열 앞부분의 "//"와 "\n" 사이에 위치하는 문자를 커스텀 구분자로 사용한다. <br>
+
+예를 들어 `"//;\n1;2;3"`과 같이 값을 입력할 경우 커스텀 구분자는 세미콜론(;)이며, 결과 값은 `6`이 반환되어야 한다. <br>
+사용자가 잘못된 값을 입력할 경우 `IllegalArgumentException`을 발생시킨 후 애플리케이션은 종료되어야 한다.
+
+- 입력 : 구분자와 양수로 구성된 문자열 <br>
+- 출력 : 덧셈 결과
+
+### 라이브러리 <br>
+`camp.nextstep.edu.missionutils`에서 제공하는 Console API를 사용하여 구현해야 한다. <br>
+사용자가 입력하는 값은 `camp.nextstep.edu.missionutils.Console`의 `readLine()`을 활용한다.

 입력한 문자열에서 숫자를 추출하여 더하는 계산기를 구현한다.
 
 쉼표(,) 또는 콜론(:)을 구분자로 가지는 문자열을 전달하는 경우 구분자를 기준으로 분리한 각 숫자의 합을 반환한다. <br>
+
 예: "" => 0, "1,2" => 3, "1,2,3" => 6, "1,2:3" => 6 <br>
+
 앞의 기본 구분자(쉼표, 콜론) 외에 커스텀 구분자를 지정할 수 있다. <br>
 커스텀 구분자는 문자열 앞부분의 "//"와 "\n" 사이에 위치하는 문자를 커스텀 구분자로 사용한다. <br>
 
 예를 들어 `"//;\n1;2;3"`과 같이 값을 입력할 경우 커스텀 구분자는 세미콜론(;)이며, 결과 값은 `6`이 반환되어야 한다. <br>
+
 사용자가 잘못된 값을 입력할 경우 `IllegalArgumentException`을 발생시킨 후 애플리케이션은 종료되어야 한다.
 
 - 입력 : 구분자와 양수로 구성된 문자열 <br>
