Simplify numerical expressions, including those involving positive integer exponents or the absolute value,
e.g.,
[beautiful math coming... please be patient]
$\,3(2^4 - 1) = 45\,,$
[beautiful math coming... please be patient]
$\,4|3-5| + 6 = 14\,$;
apply such simplifications in the solution of problems.
