Homework Statement
Hi,
To add or subtract sig figs, it is to my understanding that the answer is reported so that it reflects the least precise number.
For the example 43.4 - 22 - 3, would I report my answer as 18 or 20?
Thanks. Any help is very much appreciated!

The Attempt at a Solution
The least precise number is 3 but I am not sure if I would report my answer with 1 or 2 sig figs. I am guessing that my answer should be 20 since it has only one significant figure as well.
