Hi! I'm programming maths programs. And I got some questions about mathematical signs.
1. Inputing suqare like a * a, It's too long when I do time-consuming things. Can it be simplified? 2. Inputing fractions like (a / b) + (c / d), It's tiring work too. Can it be simplified? 3. How can i input root? thx 4 reading :) -- http://mail.python.org/mailman/listinfo/python-list
