Common Errors and Tips (Keming, Isaac, Ying Liang)

Common Errors

1) Confused with how to expand the brackets for indices 
2) Using guess and check to obtain answers
3) Unable to obtain answers for sums with the same indices 


1) Double check using a calculator and make sure it tallies 
2) Think properly and nicely without getting angry and panic in the process as panicking will only yield useless and marks-reducing results
3) Getting used to the laws of indices
