Halloween Math Worksheets | Addition & Subtraction | Print ... - Free Printable

Now I can see the grid of addition problems clearly. Each problem is associated with a letter (D, E, G, H, I, L, N, O, P, S, V) and I need to solve each addition problem.

Let me solve them one by one:

D: 27 + 28 = 55
E: 15 + 15 = 30
G: 58 + 42 = 100
H: 34 + 27 = 61
I: 79 + 14 = 93
L: 24 + 36 = 60
N: 26 + 59 = 85
O: 18 + 28 = 46
P: 49 + 33 = 82
S: 64 + 17 = 81
V: 43 + 47 = 90

Now I have all the sums:
- D: 55
- E: 30
- G: 100
- H: 61
- I: 93
- L: 60
- N: 85
- O: 46
- P: 82
- S: 81
- V: 90

Looking back at the top of the worksheet, I need to match these sums to the letters in the order they appear in the two rows of numbers:
First row: 81, 61, 30, 60, 46, 90, 30, 55
Second row: 82, 30, 60, 60, 93, 85, 100

Let me find which letter corresponds to each number in these rows:

For the first row:
- 81 → S (from S: 64 + 17 = 81)
- 61 → H (from H: 34 + 27 = 61)
- 30 → E (from E: 15 + 15 = 30)
- 60 → L (from L: 24 + 36 = 60)
- 46 → O (from O: 18 + 28 = 46)
- 90 → V (from V: 43 + 47 = 90)
- 30 → E (again, from E: 15 + 15 = 30)
- 55 → D (from D: 27 + 28 = 55)

For the second row:
- 82 → P (from P: 49 + 33 = 82)
- 30 → E (from E: 15 + 15 = 30)
- 60 → L (from L: 24 + 36 = 60)
- 60 → L (again, from L: 24 + 36 = 60)
- 93 → I (from I: 79 + 14 = 93)
- 85 → N (from N: 26 + 59 = 85)
- 100 → G (from G: 58 + 42 = 100)

Now, putting all these letters together in order:
First row: S, H, E, L, O, V, E, D
Second row: P, E, L, L, I, N, G

This spells out: "SHELOVEDPELLING" which should be "SHE LOVED SPELLING" if we add spaces.

The witch's favorite subject in school was spelling!

This makes sense as a Halloween-themed riddle - witches are often associated with spells, and "spelling" is a play on words with "spells".

The answer to the riddle "What was the witch's favorite subject in school?" is Spelling.
