All ground symbols are the 0 V midpoint, not the negative supply rail.

Connect it, step by step

Follow the component values and pin connections

Power both rails

Connect +15 V to pin 7 and −15 V to pin 4, with a 100 nF local bypass from each rail to ground.

Set the gain

Use 90 kΩ feedback and 10 kΩ to ground; apply VIN to IN+.

Observe the output

0.20 V becomes 2.00 V ideally. Keep the input and requested output within the specified ranges.
