Mean= average =(sum of data values)/(number of data values)
Mode is the most frequent data value.
Median: Sort the data in ascending order. The element in the middle is the median.
If the number of data is odd, there will be one MIDDLE element. It is the median.
If the number of data is even, there will be two elements in the middle. Add the values of these middle elements and divide by 2. The result will be the median. It is not part of the data.

The number of combinations of n objects taken r at a time has a reserved symbol nCr. On calculators it has a special key (or shifted key) marked nCr.
By definition nCr=(n!)/((r!)*(n-r)!)=nC(n-r)
In what follows, I am using parentheses to enclose what is in the denominators). So
10!/(8!2!)=10C2 or 10C8 =45 (they have the same value)
10!/(9!1!)=10C9=10C1=10
10!/(10!0!)=1

The TI-34 doesn't work with matrices.

Even if it did, you'd have to define what you mean by "compute." There are a lot of things that can be computed from a matrix, such as determinant, row and column norms, inverse, and eigenvalues.
