((270.1 - 273.1)(2.191 x 10^-5)) / (6.712 x 10^4)
This one I am going to work without going into the fancy formula notation since it seems to not like decimals right now

Lets deal with the numerator ...
((270.1 - 273.1)(2.191 x 10^-5))
((-3 x 10^0)(2.191 x 10^-5))
multiply and add
(-3 * 2.191) x (10^0 x 10^-5)
(6.573 x 10 ^-5)

since the denominator is already a single expression ... divide and subtract
(6.573 x 10^-5)/(6.712 x 10^4)
(6.573/6.712) x (10^-5 x 10^4)
Rounding to 3 places....
(0.979 x 10^-9)
since we have to have one digit in front of the decimal place ...
9.79 x 10^-8
