    Simple method: Buy an op-amp with adjustment pins provided and follow instructions on its datasheet.

    If you don't know how to draw a schematic, how do you plan to present your result?

    MOD NOTE: Merged two threads that pretty clearly were meant to be the same thread.

    If you read a datasheet for an opamp like the TI OP-07 that has offset adjustment pins as mentioned by #12, you can learn how to adjust the offset. It is pretty simple.
