In response to the work zone:
If you live in the US go to the website for Americans with Disabilities Act. Then on that website click on JAN (you'll see the link) and you will find appropriate phone numbers for counseling and follow up regarding the process. Request from your employer to provide specific accommodations and be very specific. In the US the law is on your side. I recently went through that process and it was worth it, my employer is now ready to provide the specific accommodations that I requested.

In response to personal finances here are a few suggestions:
The good thing is that dyscalculia keeps me away from spending and making irrational spontaneous purchases.
Do not make any expenditure without first thinking them through; take time to map out anything that has to do with money.
Avoid cash transactions unless they are very plain (such as round numbers.)
Hire a trusted accoutant for taxes, it's worth the extra cost.
Be very conservative in your finances. Take plenty of time to think them out ahead of time. Keep things simple.
If you use credit cards, select one from your bank because it may be better protected; avoid handling multiple credit cards; avoid anything that sounds like a good deal because chances are it's not such a good deal. Read all the fine prints and keep transactions simple.
For banking I tried a software program but it was an absolute nightmare so I went back to a time consuming but somewhat manageable paper-booklet and manual reconciliation. I always keep a couple hundred dollars in my account as a "cushion" so that any error does not end in penalties.
Use automatic withdrawals for regular payments (cars, insurances, etc.) so that you don't have to write the checks (I tend to bump numbers, invert them, write the number of the check in the amount to pay and so forth.)
Use a notebook to list every payment for each pay period and check them off every time you make the payments. A friend of mine who is not dyscalculic did that for me years ago (I was then struggling to stay afloat total chaos) and since then I have used the system that she put into place for me, with a simple notebook and a pencil, and a caculator with big and simple buttons.
Stay away from financial advisors unless they are legal, highly recommended by sound sources and totally objective.
Be organized, concrete, and give yourself time to process your finances.
