It seems you are trying to express a mathematical expression. Let’s break it down:
You have:
10, d, plus, d, minus, 2, which can be written mathematically as:
\[ 10 + d + d - 2 \]
This simplifies to:
\[ 10 + 2d - 2 \]
Then combining the constants gives:
\[ 2d + 8 \]
Now, if you want to write it as \(10 + d + d - 2\) and have a relation with "d10d," it might be a miscommunication, as "d10d" isn’t clear in standard notation.
Please clarify if this is what you intended or if there's more specific context to your question!
