Step-by-step explanation:
1. You first do what’s in the parentheses (in this situation, there are none)
2. Second, exponents (again, there are none)
3. Third, any multiplication or division (whichever comes first) from left to right (-25 x 0 =0)
4. You now have 50+50-0+2+2
5. Fourth, you do addition and subtraction from left to right, 50+50 = 100
6. Now you have 100-0+2+2
7. This gives you the correct answer of 104
