    >> 3 + 5
    ans =
        8
    >> 1 + 4 * 3
    ans =
        13
    >> sin( pi )
    ans =
        1.2246e-16

  • But, and more usefully, you can also write text files containing whole series of commands and run them
  • These files of saved commands are programs
• Next
  • Background on computers
