Problem Overview:
The task involves solving mathematical problems using musical note symbols. Each symbol represents a specific numerical value, as defined in the table at the top of the image:
-
Semibreve (𝄻): Value = 4
-
Minim (𝅗): Value = 2
-
Crotchet (𝅘): Value = 1
-
Quaver (𝅘𝅥): Value = 1/2
We need to substitute these values into the given equations and solve them step by step.

Solution:
####
Equations 1–10:
1.
Semibreve - Minim =
\[
4 - 2 = 2
\]
2.
Semibreve + Minim =
\[
4 + 2 = 6
\]
3.
Minim + Minim + Minim =
\[
2 + 2 + 2 = 6
\]
4.
Semibreve + Semibreve - Minim =
\[
4 + 4 - 2 = 8 - 2 = 6
\]
5.
Semibreve - Quaver =
\[
4 - \frac{1}{2} = 4 - 0.5 = 3.5
\]
6.
Minim - Crotchet =
\[
2 - 1 = 1
\]
7.
Semibreve + Quaver + Quaver =
\[
4 + \frac{1}{2} + \frac{1}{2} = 4 + 0.5 + 0.5 = 5
\]
8.
Semibreve + Semibreve + Semibreve =
\[
4 + 4 + 4 = 12
\]
9.
Minim - Quaver - Quaver =
\[
2 - \frac{1}{2} - \frac{1}{2} = 2 - 0.5 - 0.5 = 1
\]
10.
Quaver + Quaver + Quaver =
\[
\frac{1}{2} + \frac{1}{2} + \frac{1}{2} = 0.5 + 0.5 + 0.5 = 1.5
\]

Equations 11–20:
11.
Crotchet × 10 =
\[
1 \times 10 = 10
\]
12.
Crotchet + 16 =
\[
1 + 16 = 17
\]
13.
Semibreve - Minim =
\[
4 - 2 = 2
\]
14.
Crotchet × 3 =
\[
1 \times 3 = 3
\]
15.
20 - Minim =
\[
20 - 2 = 18
\]
16.
15 + 3 + Crotchet =
\[
15 + 3 + 1 = 18 + 1 = 19
\]
17.
Crotchet + Semibreve =
\[
1 + 4 = 5
\]
18.
Crotchet × Crotchet =
\[
1 \times 1 = 1
\]
19.
Crotchet × 5 =
\[
1 \times 5 = 5
\]
20.
Semibreve + 2 × Minim =
\[
4 + 2 \times 2 = 4 + 4 = 8
\]
