15.  Explain why do people clear the screen multiple times when using a calculator?

The older version of calculators have several “cancel” button (C, CE). The CE
button will only clear the last entry but does not interrupt with the current
computation.  For instance, if you enter 2+1 and then press CE, it would show 0, but the calculator expects a second operand for the addition. (2+ is still
there in memory). So to ensure that nothing remains left in memory and to
start a new calculation we often see people hitting clear button couple of
times. It is not due to a flaw in the calculator’s design.

16. Mention why is the mouse cursor slightly tilted and not straight?

During beginning of mouse technology, it was found that given the low

cursor. Also, the tilted arrow can help the click position easier to calculate
because the origin of the cursors bitmap was in the upper left. This saved the
mouse tracking subroutine a calculation on every click.
