Should rounding be done at the end of calculations?
Yes. You always round at the end of a calculation. If you begin rounding in the middle, your answer will be incorrect, because every number matters. You also want to take significant figures into account, unless you're given how many places to round to.
What does interpret with remainder mean?
Done the calculation (get the answer) and also show the remainder (don't round up or down).
How can using the over 5 rule be misleading in math?
Rounding up when the last digit is over 5 can artifically inflate the resulting number, particularly if you round at every intermediate calculation. In general, students are advised to maintain all digits throughout the calculation and to only round the final result.
What is the circumference of a 4 inch round circle?
The circumference of a 4 inch round circle is: about 12.57 inches. You can easily do this calculation for other circles by multiplying the diameter by Pi (about 3.1416).
When to use rounding?
There are two main situations.when one (or more components) in a calculation is given in rounded form, it will limit the accuracy of the answer. For example, if you use pi = 3.1416 then the calculated area should not have more than 5 significant digits.if the answer to an exact calculation is a long decimal string - particularly an irrational number.
In performing a multi step calculation when should you round off the answer in the calculator display?

How do you estimate to check that your answer is reasonable?
To estimate an answer the numbers are rounded and the calculation done. It is often suggested to round to 1 sig fig as this will give a general indication of how big the answer should be. eg 1234 ÷ 31 → 1000 ÷ 30 ≈ 33.33 so an answer in the region of about 30 to 40 is expected. A slight variation from this can make the calculation easier, eg rounding the 1234 above to 2 sig fig gives 1200 ÷ 30 which is easier as 1200 is a multiple of 30 (and actually much closer to the real answer) giving 1200 ÷ 30 = 40; the real answer is approx 39.81.
How are daily and monthly temperatures calculated?
The calculation for a daily average is as follows: Add the day's maximum and minimum temperatures, divide by 2 and round to the nearest whole number. The calculation for a 31-day month, add the 31 daily highs and 31 daily lows, divide by 62, and round to one decimal place.
What is the circumference of a 13 inch round circle?
The circumference of a 13 inch round circle is: about 40.84 inches.To do this calculation for other circles, just multiply the diameter by Pi (about 3.1416). The result is the circumference.
How do you estimate multiplication problems using front end estimation?
Its approximate calculation. You round up or down and leave one significant figure on all numbers in the calculation. Say its 2354 * 128 So: 2000 * 100 = 200000
