**Note mistakes I made in this in class: in 1), -260 0F
should be -260. 0F (indicates 3 sig. figs.); in 4), answer
is 0.0202 - 3 sig. figs. The point is that when subtraction of two
large numbers yields an answer much smaller than either, the sig. figs.
in the answer may be smaller than in either. 62.35(4 sig. figs.) -
61.17 (4 sig. figs.) = 1.18 (3 sig. figs.) The precision limit is in
the second decimal place throughout.**
