Split the second number such that one of the two splits added to the first number is 10. Then add the remaining split to the 10
7 + 6
= 7 + 3 + 3
= 10 + 3

logarithms (and exponentials) are a thing that we rarely encounter. Even I am pissed when I have to use them every year or so. You should be discouraged if you have a math major and/or are in a position where you need it daily.

If it's any solace you should know that there's next to no correlation between mathematical prowess and computational speed, else this guy is your new euler

My computational speed component of IQ is subpar, linguistic component is around 125 and analytic and logical is around 140. Every time I had a math test in high school I would get as many of the right answers as the two smartest guys(one is studying math in college and the other got into medicine rn)but took much longer than them. The only time this didn't happen was due to them not even opening their notebooks and me actually applying myself on the test on logarithms and integrals(I still remember the stupid distraction mistake that I had on that integral test, I forgot to put a number which I put in the step before that)
I feel your pain.

I played some board games with a buddy last week. I'm slow as fuck doing basic arithmetic in my head. Much slower than I was in fucking sixth grade. I can do algebra and calculus decently, but now I feel like a retard when I have to add together a bunch of 2 digit numbers without a calculator.

I always fall back on field axioms.
Any natural number can be expressed as "1 + 1 + 1 + ..."
So for 7 plus six I just write it out.
1 + 1 + 1 + 1 + 1 + 1 + 1 +
1 + 1 + 1 + 1 + 1 + 1 + 1
= 1 + 1 + 1 + 1 + 1 + 1 + 1 +1 +1 +1 +1 + 1 + 1
Which is the definiiton of 13.
