When I’m doing woodworking and I need to add up some very simple measurements I always use a calculator. I could very easily do it in my head and often automatically do without even thinking about it. However I’ve learned the hard way it’s very easy to make a simple error with even something as simple as 8+7 and chances are you won’t find out till later when two parts don’t fit together. That’s 20 hours down the toilet, just because I didn’t double check using the shop calculator.
I’m alright when it comes to mathematics, but my memory is a swiss cheese. I’ll do a calculation, context switch and 3 seconds later it’s either gone or I remember incorrectly. Having things written down, on paper or in a calculator, gives peace of mind.
Totally this. Find an online calc that accepts fractions and just get it done right in a few seconds vs trying to convert to 16ths or some crap. Which is why I use all metric unless I’m forced into imperial units.
