Elizabeth has 14 boxes of cookies each box has 28 cookies how many cookies does she have

aev [14]

We calculate this by multiplying the number of cookies by the number of boxes:

28*14=(20+8)*14=280+80+32=360+32=392 (that's how I like to count it, there are also other methods)

so she has 392 cookies in common.
