Answer: To square a digit you must multiply LxH= N² (number)

4582.197- 5x5= 25²

12) Question: Divide the number of the day by 3.55 and round to the nearest hundredth.

Answer: 1290.7597 You must raise the nine by one, because 7 is "5 and higher", which means you must make the nine a zero and add 1 to the 5. You will end up with the answer as 1290.760 or 1290.76

Remember: Here is a poem about rounding numbers; Find the number in its spot.

Go next door and see what you've got. 5 or more raise the score, 4 or less let it rest.
