TI-30X Pro, original and useful toggle buttons
I own several scientific calculators from different brands. I have no preferences and no one pays me to speak well of one model and badly of another. That said, I try to point out the good things I notice from time to time in this world. I noticed that the TI-36X Pro or TI-30X Pro (TI-SmartView in figure) have a unique way of choosing between various alternatives. For example, you just need to press the same key (showed in red) several times to switch from the natural logarithm to the base 10 logarithm to the base to be defined (toggle key). I haven't seen this in other models/brands, and I consider it a simple and intelligent solution. It occurs to me that something similar could be applied to the conversion of decimals into improper fractions and mixed fractions. See you soon for more small observations.
