SOURCE: can i do sigma notation
No. There are some keys on the TI-30XA that may make you think so, but they are statistical operations. For example, you can enter values using the Sigma+ key and the TI-30XA can give you the sum of the values entered, sum of the squares, mean value, standard deviation and so on.
You cannot do calculations like "Give me the sum of all integers from 1 to 100" with the TI-30XA, you'd need a far more sophisticated calculator.
