Question

tom is putting cartons of ice-cream in one of the freezers.There are 13 boxes and each box cantain 24.How many cartons of ice cream carton are there in total.

Answer 1

24 ice-cream cartons in a box, and you have 13 boxes.  Therefore, you do 24 times 13. 

24 x 10 = 240. 

3 x 4 = 12
(3 x 2 = 6) x 10 = 60. 

  240 
  +60
  +12
=312

Tom has 312 cartons of ice-cream
