This hits the nail on the head:
1 (person at table A) / 3 (people at table A) can't be added to 1 (person at table B) / 3 (people at table B) without conversion of units.
- dwild 6y agoAnd then it's easy to make them see how her answer was right in its own way by adding another unit, (person at table a+b and people at table a+b) and show why it may be harder to works like that for now. I heard so many people complains that each year in maths they would essentially learn that everything they learned the year before was wrong... can we fix that please?!
