Как оргонизовать сесии в калькуляторе...

[bobrdobr94]

Привет всем!
Есть одна задача: есть калькулятор дробей (+ - * /) но работает он так ввели числа посчитали. и заново ввели новые числа посчитали нужно что бы посчитали к примеру 2 + 3 нажали * и результат переносится в блок умножения вот код: пока выложу только + усли нужно выложу все
