Of course I have tips.
Start here and do it exactly as stated:

The reason is simple. Automate, automate, automate!
Funny thing. While checking my own process, I realize that I do something different compared to this website.
When adding numbers with a carry, I do the carry first and then work on the next row. Instead of “+7”, if the rod is full I change to “+10-3”.
The rules state that it needs to be done in reverse. So first do the -3 and then +10. I automatically do +10 first and then -3. Fir me this feels natural. However; the rules dictate reversed order.
There might be a good reason that I don’t know of; I still advocate following the site, even if there is this one rule that I do differently 
Also read this thread again. It is jampacked with tips:
