From now on, the "+" symbol no longer means to combine the count of objects (e.g. 3 things plus 4 things make 7 total things would not be modeled as 3 + 4 = 7).
Instead, the use of the + symbol is to show 5 + 3 = 7 to resolve the question of "how many spaces between objects are created when you line up five things and three things"
(ex: t _ t _ t _ t _ t _ t _ t _ t ) and this is now to be considered addition
If the other basic computational symbols maintained the same relationship to addition as they had before this new convention what would be the answers to the following problems?
4 - 3 = ?
3 x 3 = ?
9 / 3 = ?
sqrt (36) = ?
