Answer 1

 trial balance is a basic accounting tool that lists all of a business's credits and debits in two side-by-side columns. If there are no errors, the two sides of the trial balance will be equal. An unequal trial balance indicates some sort of error, but even an equal trial balance can hide other types of accounting errors.  These are the possible errors to be made:  wrong columns,wrong amounts or typographical error and arithmetic error
