    Algebraic statement

    Hi all,

    I'm learning programming at the moment but my maths has never been great. They often use statements but they keep using one which I cannot get my head around which could for examlpe be:

    x=3
    x=x*17

    What i don't understand is if you sub in 3 for x in the 2nd statement then the statement would read:

    3=3*17

    How is that possible that 3 can be equal to a number other than 3? It doesn't make sense to me at all???

    Really appreciate any help.

    Thanks

    Hi

    In that case what they are stating is the following:-

    Take the value in the variable called X, then multiply by 17, and store the result back into the same variable (x). So to start with x=3, when the statement has finished then x will equal 51.

    Cheers!

    This is programming not mathematics. Here "=" is the assignment operator not an equality sign. Other languages will use ":=" or even "<-" to indicate that this is not an equation but an assignment.
