Why don't Google Spreadsheets put a minus?

Question

Google Sheets

the forumla is banal =A1-B1
A1 = 5000
B1 = 1000
if B1-A1 (5000-1000) = 4000.
and if in B1 the number is greater than the number in A1, then it turns out for example (5000-8000) = 3000, but it should be - 3000!
WTF?

Answer 1

Check the format
Expand the cell
Try an expression like "=-1*3000"
