Simple computations in biomechanics problems are often performed
quickly and easily with a hand-held calculator. However, the correct
result can be obtained on a calculator only when the computation
is set up properly and the rules for ordering of operations are
followed. Most calculators come with an instruction manual that
contains sample calculations. It is worthwhile to completely familiarize
yourself with your calculator’s capabilities, particularly
use of the memory, before using it to solve problems.
