25 using BODMAS
Depends if you're following BODMAS.
BODMAS would make the answer 25 (if I've remembered it right)
5 X 5 = 25
25 - 5 = 20
20+5 = 25
I now await being told I'm wrong
Using Bodmas is -15. The Sum is still the same. You don't process them as individual entities. It is an order in which you do things.
5x5 = 25.
Then you subtract the 25 from 5 giving you -20.
Then you add the 5 giving -15.
Five or zero?
