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.

this little casio calculator is the perfect size to keep closeby whenever i need it.it's easy to use, %26 the number screen is easy to see. the buttons are large enough so that i don't press 2 buttons at once. the price is really worth buying this. i hope it lasts a long time.

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.
