Question: I was just surfing a social site and found this question posted by someone. People were arguing or different answers like 80, 100, 120. So, what is the correct answer for $10 \times 10-10+10$?

I used order of operations (BODMAS) and got that the answer is 100. 
Am I right?

Answer: 
Its 100. You will first execute the multiplication and then the minus and plus.
$$
10 \cdot 10-10+10 = 100 - 10+10 = 90 +10 = 100. 
$$

Multiplication first, then addition and subtraction in the order they appear left to right is what you get by applying PEMDAS.
