I turn 48 into 50 and 27 into 30 and get 80 then take the 5 I added in the beginning away and get 75

I think " 4' plus 2' 3" = 6' 3" (six feet, three inches)

I reach for my phone and hit the calculator app

@Tim Hager same for me.

@Jim K.

I would take the 23 and subtract 7 and then multiply by 4 to get the approximate square footage of my yards seasonal rain fall in the post monsoon quadrant...

But on a more serious note I would just take out my phone and use the calculator. Cuz I HATE math...

I take 48 then add 30 to get 78 then I just subtract 3 because I used 30 number instead of 27

This sounds crazy but it’s much much faster in my mind to do math this way

I Add The 7+8 drop The 5 AndCarry The 1

@Jim K. 48+20 =68 + 7 = 75

My brain sees the 15 and then the 60.

Then it’s an easy add to 75
