    That is wrong. What are those single letter variables?

    Do you mean the variables in i and j?

    if so i is the row and j is the column ohhh, so

    create row
    create column

    create x and get y to compute location ????

    create i
    create j
    perform i * j
    add (i * j) to list

    None of the above makes any sense to me. If i and j are the loop variables, what does "create" mean?

    create x
    You would compute the value of x outside the inner loop because it would apply to all the shapes being created in the inner loop.

    perform row * ROWSEPARATION + ROWZERO
    perform column * BLOCKWIDTH
    (add row and column) add to list location
    These make no sense to me. Can you explain what each of them means?

    Is Y also computed outside the loop?

    It says that:
    The i'th row of blocks has its upper edge aligned with i (row) * ROWSEPARATION +ROWZERO.

    The j'th column of blocks has its left edge aligned with j (column) * BLOCKWIDTH

    since the column depends on the row , row + column would be the answer

    How can it? It is where the shapes go on the current row.

    Look at the drawing you made of the grid you are building. See how the values of the locations where each shape goes relates to the row and column and how the values of the uppercase constant variables determine where the next shape goes.

    When row is at 0 the row goes to 50
    When column is at 0 the column goes to 0

    When row is at 1 the row goes to 100
    When the column is at 1 the column goes to 50

    The row is always ahead of the column by 50 atleast so no errors would occur

    None of those last two posts makes any sense to me.

    That's it for tonight. Back tomorrow.
