estimate.State your standard(rounding,front-end, or clustering.)
91.7 + 88.6 + 89.1 + 92.52 + 90.6
3.9 + 8.1 + 2.06
Please and Thank-You
Standard = what process you always use. For example, if you always round up for 6 or .6, etc., then that's your standard. Using that standard, then you'd have the following:
92 + 89 + 89 + 92 + 91 = almost the same as 5 x 90 = 450 (estimated)
4 + 8 + 2 = 14 (estimated)
Someone else may have further or different information, but this is what my grandchildren have been studying.

I searched Google under the key words "math rounding clustering front-end" to get these possible sources:
