Whats your reaction to it? How can this be true?

25-55+(85+65)=120
5!(factorial)=5*4*3*2*1=120
so,
25-55+(85+65)=120=5!
it's true.

If you read the question again, you will probably notice the slight trick used in this question.

25 - 55 + (85 + 65) = 25 - 55 + 150 = 120

Now, 120 is also equal to 5!

5! = 5 * 4 * 3 * 2 * 1 = 120
Yes, we were talking about 5! (factorial) and if you read the question, thats what is written there.
