71-5-9+2xx2 = 61
or simply:
71-5-9+2+2 = 61
Explanation:
Multiplication takes precedence over addition or subtraction.
Once you are left with a sequence of additions and subtractions, work from left to right.
71-5-9+underbrace(2xx2)_xx
=underbrace(71-5)_(-)-9+4
=underbrace(66-9)_(-)+4
=underbrace(57+4)_(+)
=61
Or:
=underbrace(71-5)_(-)-9+2+2
=underbrace(66-9)_(-)+2+2
=underbrace(57+2)_(+)+2
=underbrace(59+2)_(+)
=61
