Emma bought 3 dozens of macarons in addition to her 10 pieces of macarons for a party. If 15 pieces of macarons are left over, how many pieces of macarons were eaten?
Three dozens of macarons are equal to 3 x 12 = <T>multiply(3, 12)=36 pieces of macarons.
So Emma has a total of 36 + 10 = <T>add(36, 10)=46 pieces of macarons for the party.
Therefore, 46 - 15 = <T>subtract(46, 15)=31 pieces of macarons were eaten.
