2. INSTRUCTIONS INTRODUCTION This game is a practice to round off. All you have to do is read the description and answer the question correctly. DEFINITION OF ROUNDING ROUNDING MEANS REDUCING THE DIGITS IN A NUMBER WHILE TRYING TO KEEP ITS VALUE SIMILAR. THE RESULT IS LESS ACCURATE, BUT EASIER TO USE. THIS IS THE COMMON METHOD * DECIDE WHICH IS THE LAST DIGIT TO KEEP * INCREASE IT BY 1 IF THE NEXT DIGIT IS 5 OR MORE (THIS IS CALLED ROUNDING UP) * LEAVE IT THE SAME IF THE NEXT DIGIT IS LESS THAN 5 (THIS IS CALLED ROUNDING DOWN) EXAMPLE: 243 ROUNDED TO THE NEAREST TEN IS 240 (BECAUSE 3 IS LESS THAN 5) MATHSISFUN.COM Back Back :
