University calculators

[SlideRule]

My reticence to contribute to this thread has abated (perhaps to my detriment), so …
a) analytical vs numerical former is less 'calculator' dependent than the latter
b) integer vs decimal ALL integers have infinite precision whereas …
c) units of measurement
d) rate functions

A: has the calculator degenerated into a crutch - strong indications this statement is more than an observation (ie. has valdity).
B: I use integer math almost exclusively and resort to decimal math predominately for either convenience or simplicity {related to d)}
C: my physical Science (B.S.) / Civil Engineer(B.S.) education was replete with UNIT analysis for nearly ALL my computations / calculations {time, mass etc.}
D: rate functions and engineering analysis are nearly synonymous.

The calculator is adminicle to analysis and should follow, not precede, an initial estimation of a calculation / computation. I seldom put to record a computation in the same manner as I deploy to verify / quantify that computation, especially with the assistance of a calculator.

rebuttals / alibis /thoughts welcome!
