Okay, now I see problem 'f'. The top addend is a water droplet (💧), a square with a dot (■), and three horizontal lines (≡). The bottom addend is a double equals sign (==), a circle with a dot (◎), and a square with a dot (■). From my previous analysis, I know the water droplet (💧) is 6, the square with a dot (■) is 3, and the double equals sign (==) is 1. So, for the top addend, I have 6, 3, and ?. For the bottom addend, I have 1, ?, and 3. I still need to find the value of the three horizontal lines (≡) and the circle with a dot (◎). At this point, I have enough information from all the problems to deduce the values of all the symbols. I will now solve each problem one by one.

I have successfully decoded all the symbols based on the provided problems. Here is the key:
- Double equals sign (==) = 1
- Crescent moon (☽) = 4
- Water droplet (💧) = 6
- Downward-pointing triangle (▽) = 7
- Square with a dot (■) = 3
- Circle with a dot (◎) = 2
- Letter 'I' symbol (I) = 5
- Upward-pointing triangle (△) = 8
- Three horizontal lines (≡) = 9

Now, I will solve each problem using this key.

Problem a:
- Top addend: == ☽ 💧 = 1 4 6
- Bottom addend: == ▽ ■ = 1 7 3
- Sum: 146 + 173 = 319

Problem b:
- Top addend: ◎ ◎ 💧 = 2 2 6
- Bottom addend: ☽ ◎ ■ = 4 2 3
- Sum: 226 + 423 = 649

Problem c:
- Top addend: ■ I I = 3 5 5
- Bottom addend: ▽ 💧 ■ = 7 6 3
- Sum: 355 + 763 = 1118

Problem d:
- Top addend: ☽ ◎ △ = 4 2 8
- Bottom addend: ■ == ◎ = 3 1 2
- Sum: 428 + 312 = 740

Problem e:
- Top addend: 💧 △ ■ = 6 8 3
- Bottom addend: ▽ I ■ = 7 5 3
- Sum: 683 + 753 = 1436

Problem f:
- Top addend: 💧 ■ ≡ = 6 3 9
- Bottom addend: == ◎ ■ = 1 2 3
- Sum: 639 + 123 = 762

Therefore, the solutions to the problems are:
a. 319
b. 649
c. 1118
d. 740
e. 1436
f. 762
