Numbers that end in a digit of 5 or more should be rounded UP to the nearest ten.

Example: 28 rounded to the nearest ten would be 30

When you decrease both addends when rounding to add, the estimated sum will also be decreased. Rounding down the addends will result in a smaller value for the estimated sum.

841 would round down to 840 and 362 would round down to 360. So 840+360=1200. The sum is about 1200.

You can calculate 3444 times 670 without rounding or you can estimate it WITH rounding. But you cannot estimate it without rounding.

400 + 500 = 900
