I solved this problem as I knew that 𝔁 would be 7 as the bottom sum said 1 and 7x3= 21 with 2 to carry over. I did the second number in the bottom sum as 𝔁x3+2 (from the carrying over),equaled to e. I immediately knew that the answer would come to 5 as it would be 15 + 2 (from the carrying over).From 17, I carried over 1 to add back on. I continued to use this method until I reached the answer and I knew it was correct as I did a normal column addition and I reached an answer. I hope you submit my answer! :)
