mr. fernandez wants to put tiles on his kitchen floor. he has 30 tiles. mr. fernandez put down 2 rows with 9 in each row. how many tiles does mr. fernandez have left?
The answer to this problem is 12, because if he had 2 rows of 9 tiles in each it would be 9 plus 9 or ( 9+9 ) So then you would take the number u got ( 18 ) and subtract it from the number of original tiles ( 30 ) getting an answer of 12 :)
