Tutorial:

** Typo in the slides on the left. Should be 'x(i)>0 | x(i)==0'

Tasks:

1. Use a For Loop to calculate the summation of [2 5 6 7 8 8 10 11];

2. Count how many positive numbers are in matrix [4 5 6 7 8 -2 -1 0]; Calculate the avaerage of the positive numbers.

3. Use a For loop to find the maximum value in [4 5 3 2 32 33 45 1 2 ];

4. Use nested For Loops to find the number of negative values in [1 2 3; -3 4 5; 9 -5 3]. (Probably need two counters)
