Answer 2

I find it convenient to rearrange the numbers so that positive numbers are added, negative numbers are added, then the two sums are added. Of course, you can do it any way you like. Your calculator does not care about the order of the numbers you enter.

... = (1.4 +1.8) -(5.5 +1.73 +1.09)

... = 3.2 - 8.32

... = -5.12
