Likely finger counting. The base 60 system likely originated from ancient peoples using the digits on one hand to count.

With the left hand, the left thumb counts up to 3 knuckles on each finger for a total of 12. Then with the right hand, the right thumb counts each additional finger as +12. Five multiplied by 12 equals 60.

That's how I first learnt about it.

Use your thumb to point/count your other joints in the fingers (including the base) and you can count to 12 on one hand. If you do the same with your other hand you're able to count up to 144 with just two hands.

how do you get to 144? Isn't it 60 on each hand?

12*12 == 144

I assume you multiply the two hand values when you are using two.

Counting 12-15 per hand was how I grew up learning, I thought this was the way everyone did it?

My education experience in the US was only 5 for each hand - I resent not learning about this for so long because I definitely could've used it countless times.

Time to build muscle memory...
