The are four opamps on the chip.
The +(-) designators are the noninverting(+) and inverting(-)
inputs. The corresponding out number is a output.
i.e. IN1(+),IN1(-),OUT1 are one opamp.
Don't forget to wire the power pins :) at a voltage appropriate for your system and the spec sheet.
Words of advice (warning).
Connect unused outputs to the corresponding IN(-).
Connect unused INx(+) inputs to "Gnd"; a voltage half-way between Power + and -.
Given your knowledge level: Read the data sheets, and your
course material carefully and think. The ideas are simple but recquire a certain "idea" that you must work on.
If you don't have course material; I can probably find expalnations at the Analog Devices site or the National Site.
