Solving: First I used the first clue to figure out what is ! and #. I evened it and got the following results !=25 and #=1. After that I used the second clue by taking away 25 from the total and was left with 15 then I divided that by 3 because there were 3 symbols and got @=5. Then I added them all up: 25 + 5 + 1 + 1 + 1 = 33.
Conclusion: So the answer was 33.
