Texas Instruments TI-30XB Multiview

I have a calculator from Texas Instruments that has been running on the same battery for 15 years, and it still works! Really unbelievable! I now needed an advanced calculator and you guessed it: another from this brand of course.

A real pleasure to work with because of the user-friendliness and the many options. I especially like the larger screen. It saves a lot of writing and gives you the opportunity to work more efficiently.

I already had one for school, but now I also ordered one for my sister. It is a very nice thing, you can make tables, the shift functions on the buttons as extra are logical and as it were the reverse of the normal button, for example: the root (which you get by shifting in pressing) is at x-squared. A logical choice. You can also enable the Mathprint function, so you get calculations exact, so with fractions and square roots, so you don't have to round. Furthermore, the battery life is very good. I've had mine for two years (!) without ever replacing the battery, and it seems like I still won't have to for a while. The only drawback is that there is no sliding valve, which is just that little bit easier. I now also have the Texas Instruments 84p plus ce-t for school, the transition is not difficult, given that the key layout is very similar to the Texas Instruments 30XB Multiview. Furthermore, a fast, good and above all pleasant handling of Coolblue. And I had it at home the very next day! Tip: sign up for the newsletter, you will receive a gift voucher worth 5 euros.

super good basic calculator and does what it's supposed to do well. Some minor drawbacks: When an adjustment is needed in the middle of a formula, this machine removes the number that was in that position instead of moving it 1 position back, so that you often have to re-enter the formula from the adjustment. the square root of 2X260 is shown as 2Xsquare root of 130. Only after pressing the key with 2 opposite arrows you get the numerical answer.
