Let's break down the problem step by step:

1. The bookstore sold **28,346 math notebooks**.
2. They sold **7,218 fewer dictation notebooks** than math notebooks.
3. They sold **2,034 fewer biology notebooks** than dictation notebooks.

### Step 1: Find the number of dictation notebooks sold
Since there were 7,218 fewer dictation notebooks than math notebooks, we can calculate the number of dictation notebooks as:
\[
\text{Dictation notebooks} = 28,346 - 7,218 = 21,128
\]

### Step 2: Find the number of biology notebooks sold
Since there were 2,034 fewer biology notebooks than dictation notebooks, we can calculate the number of biology notebooks as:
\[
\text{Biology notebooks} = 21,128 - 2,034 = 19,094
\]

### Step 3: Find the total number of notebooks sold
Now, we add up the number of math, dictation, and biology notebooks:
\[
\text{Total notebooks} = 28,346 + 21,128 + 19,094 = 68,568
\]

### Final Answer
The total number of notebooks sold is **68,568**.
