Question... If you had a drawing of an open array with 4 rows and 6 columns, what would you accept as an appropriate equation to represent that array? a. 4x6=24 b. 6x4=24 c. both a and b Basically, my question is: Does it matter if the number indicating the rows (or columns) comes first in the equation, or is either one acceptable, based on the commutative property of multiplication and congruency?
