That said, if there are several complicated operations involved, sometimes it's faster to plug in some "easy values" (e.g., 0, 1, -1, etc) to see if you can reach a solution faster.

## Just wondering... Is it a

## That's a good strategy.

That's a good strategy.

Of course, if you get the same outcome with 1, -1 and 0, try 1/2, -1/2, 10 and -10, to see if you get a different outcome.

As mentioned in the video, plugging in numbers has its limitations since you will never by 100% certain of your answer UNLESS you're lucky enough to get two different outcomes (which means the correct answer is D).

## Sir for this quantity just

E.g. 1&-1,10&-10,1/2&-1/2 with 0 with all to confirm our answer

## You're referring to the

You're referring to the question that begins at 0:10. Yes, plugging in those two values will work for that question to determine that the correct answer is D.

## Thank you sir
