You can solve this one with redneck math. You simply flip the numbers in 7+6 upside down, which looks like 4+9, which is clearly 13.

For anything times 5, I just take the other number, half it, and then multiply by 10. Voila. Times 5.

In my head: 7 + 6 = 7 + 7 = 14 - 1 = 13

Ha! You made me think the exact same phrase twice!

@Maven Yet another "wait, normal people don't do this" moment for me...

Dude trying to get it from first principles!
Which is what I also lean towards. Give it to me step by step and I need to clearly map out each one... then the mind wanders and when I snap back to attention, I've lost the plot already, my mathematical surroundings are unclear, disorienting.

Add to this an erratic series of math teachers - some of them good, some of them blah - and this day trigonometry to me is a jumbled mess, but I loved calculus and was pretty good at probability and statistics.

If you know those five intuitively, adding and subtracting become automatic even with adhd.

1 + 9 = 10

2 + 8 = 10

3 + 7 = 10

4 + 6 = 10

5 + 5 = 10

These ADHD memes hitting a little too hard

7+7-1=7+6, if you can't remember what 7+6 is, it's pretty convenient.

Omg i think I have adhd

I've got an idea for a meme for you:

ADHD be like: Man puts on pants
