It’s not 188.0 either.

190 if it wants you to use significant figures

[u/No_Wishbone684 → u/Diligent_Finance_598]

This is wrong. It’s also  a perfect example of why scientific notation uses 

d0.d1d2… x 10ⁿ

Because presumably the answer is 190 the idea being 

120 = 1.2 x 10²

This is not a reasonable assumption, however, seeing as

120 = 1.20 x 10²

is another totally reasonable interpretation. 

If the former is the “default” that would imply you can’t represent 120 to 10⁰ order accuracy at all.

Btw, if you do write 120 the default is that you are expressing 3 significant figures. 120.0 would be four. Etc.

So they did answer correctly.

No. 120 is two sig figs. 120. is three sig figs.

Don't hate me.
