## 19단 Description
19단 학습을 흥미로운 시각화 경험으로 바꿉니다.
모든 연령을 위해 설계되었으며, 기하(배열, 면적 모델, 직사각형 그리드)를 활용해 숫자가 어떻게 결합되는지 보여 줌으로써, 
단순 암기가 아닌 ‘곱을 눈으로 이해’하도록 돕습니다.

기능
- 기하 기반 학습: 곱을 면적으로 시각화하고, 직사각형 분할로 인수를 분해하며, 패턴을 암산과 연결
- 즉각적인 피드백이 있는 인터랙티브 연습
- 오답 기록 및 복습
- 결과 피드백 및 PDF 인쇄 기능

Multiply Fun과 함께 곱셈의 마법을 경험하세요!
