Now, let's talk about increases and decreases. Imagine you're at a store and you see a sign that says "20% off" - how much would you pay for a $100 item? That's right, you'd pay $80! To calculate this on your calculator, simply enter 100, press the percentage key, enter 20, and press the minus sign - easy as pie!
