I fully understand the order of BODMAS - It's the order of operations in maths equations.

So lately this little puzzle/riddle has been going around on social media - Solve carefully - 9GAG . I understand that it's a play on grammar because they actually mean 5! as in the factorial.

The thing i notice is that some people argue that the answer is -180 and others argue that it's 120 - for the simple adding and subtracting, not the factorial itself.

25-55+(85+65)

25-55+(150)

25-205

=-180

Others state

25-55+(85+65)

25-55+(150)

-55+150+25

-55+175

=120

Which is correct and why?

Thanks

Ps. I feel quite silly for asking this.
