Flexible, advanced, and despite its 470 functions still easy to use, this scientific calculator covers all the needs of daily school and university demands!
- Two-line display showing equation entered on top line, and answer on the bottom line allowing users to check both the equation and answer at the same time. User can amend the equation if needed.
- Solar powered with 1 x LR44 battery as backup, calculator can be used both during the day and night. Battery is secured with child-safe lock. Operating time is approximately 5000 hours, using the alkaline battery only. Auto power off after approximately 10 minutes.
- 9 values can be stored in calculator, with 8 temporary memories and 1 independent memory.
- Can perform 470 advanced scientific functions.
- Converting decimal to scientific or engineering notation.
- Allows you to enter numbers and equations as fractions.
- In addition to the four basic arithmetic functions (excluding division between matrices), X3, X2, and X-1, users are provided with transpose and cumulative matrix functions.
- Calculating complex numbers (in the form of a + bi).
- When a series of bivariate data has been entered correctly, then the calculator can be used to find the values of a and b, to give the equation of the line of regression from which we can make estimates of the variable y of the equation y=a+bx.

No problems after a year and a half
Color: Dogwood & Calming, Size: Medium
Have been regularly buying these for my corgi for about a year and a half. The 2 pack lasts about a month or 2 each time. Pieces break off in small enough pieces that they safely pass through his digestive system. He gnaws each one down to about 1/4 the original size before we take it away and give him a new one. He continues to have regular bowel movements and has a healthy appetite so I can’t imagine any problems arising after so long.
I have tried other alternatives and every other similar chew breaks off in larger pieces and didn’t feel comfortable letting him chew/eat them. I noticed there are a few 1 star reviews saying their dogs got sick off these but after a year and a half I have had 0 issues with this product. I guess it depends on the dog and how big of pieces they are swallowing. My dog ingests pieces about the size of a grain of rice so just pay attention and you should be fine.

Long lasting and safer alternative to sticks
Color: Dogwood & Calming, Size: Medium
These are great, very durable, and have lasted a very long time. Much safer for my dogs than the random sticks they find in the yard. They do get shorter with chewing eventually, but they don't break off in little chunks like I've seen with some nylon chews, and they don't splinter like wood. Medium size works well for both my 16 lb Cavalier and my 60 lb Pyrenees/Golden mix. They're both moderate-to-aggressive chewers, though size obviously affects how much damage they can do.
I wish you could buy the hemp chew separately because that one is very much a favorite in my house, so after 2 years and 2 purchases, I have barely any left of the remaining hemp chew, but still 2 of the dogwood chews that neither dog is as interested in anymore. I'd love to buy a couple more of just the hemp one.

Your dog will thank you.
Color: Dogwood & Fresh Breath, Size: Large
My dogs loves to chew on these. They make a small mess but not as bad as other chews. They are food for keeping teeth clean.

Nice chew toy
Color: Dogwood Mushroom, Size: Medium, Color: Dogwood Mushroom, Size: Medium
Super durable and puppy loves it. It was a bit hard for her at first but now at 5 months it’s one of her favorite things to gnaw on! It is heavy for the size but seems to be great quality and has given many hours of chew time with minimal wear.
