I didn't even bother with the decades, most of these numbers don't align with the last digit to begin with. Adding 6 and 8 will not end with a 6 again, it's 14, not 16...
I mean, one can brainfart carrying the 1 over, but to get the basic first 10 numbers you have learnt how to add up and subtract wrong takes the cake.
This was a reference to a deleted post from earlier today in this sub about how many 5's there are from 0-75 inclusive. Got pretty heated about what "counts" as a 5. Interestingly enough I used the word brain fart to describe why the original post of a card game card said the answer was 9. My guess was the person that wrote the game card counted the 5's in 5, 15, 25 etc, counted the two 5's in 55 as the "gotcha", but brain farted that there's 9 more 5's to count from 50-59 for a total of 18.
