If your experiment did not seem to match the expected results, what did you learn from the experience?

i learnt that the different result that i got can be prepared through my experiment. if that result is useful for anywork or for me then i can note down my procedure and use it again to get that result . And while noting it down i will know about the mistake that i did due to which i got different result and i can do correction of it in next time.

just did the assignment and the answer was #1 +2 n
