In other countries, it may be called BODMAS, but the rule is essentially the same.
Multiplication and division come before addition and subtraction. When two operations have the same priority, calculate them from left to right.
That one rule is enough to solve most viral math puzzles.

Now test yourself with a similar problem:
30 + 20 – 10 × 0 + 5
Complete the multiplication first:
10 × 0 = 0
The expression becomes:
30 + 20 – 0 + 5
So the answer is:
55
Once you spot the multiplication, the puzzle becomes much easier.
The Final Answer
The correct answer to:
50 + 50 – 25 × 0 + 2 + 2
is 104.
The problem is not really testing your ability to add or multiply. It is testing whether you pause long enough to apply the order of operations before trusting the first answer that comes to mind.
