Built to Last From Real Estate to Algebra

This little Casio SL 310SV has been through it all. I first picked it up years ago for my real estate sales exam, and it was flawless, quick, accurate, no nonsense. Later, my wife used the same one for her pharmacy tech certification, and it handled all her conversions and dosage calculations without skipping a beat. Fast forward again, I used it for my real estate brokers exam, and now it's in my middle schooler's backpack for algebra homework. This thing is practically immortal. The solar and battery combo means it's always ready, even when it's been sitting in a drawer for months. The buttons still click like new, the display is super clear, and it's small enough to slide into any pocket or binder. If you want a reliable, simple, and affordable calculator that can literally go from classroom to certification exam to business life, the Casio SL 310SV is a solid choice for over a decade. If it isn't broke, then leave the SL 310SV alone. It just works.

Good for government tests

This is the perfect basic calculator for government tests. I bought this to take a HAM radio exam as they only permit basic calculators in for testing and my other calculators are considered “too advanced”. This worked perfectly as it allowed me to make the calculations I needed.

I use this calculator at my work. it's oily and I drop it at least once a day. this is my second purchase for this calculator because it's tough. I bought this one to replace the one I've had for about 4 years.the only reason I'm replacing it is because I think I spilt something in it and numbers aren't very clear anymore. It's the first one I've had that last so long
