A warm nod to arithmetic
I’m sure you noticed something curious in the last post: the equivalent (rounded to the nearest whole degree) of Thursday’s warm high temperature of 82°F was 28°C, a number consisting of the same two digits but in reverse order. Some of you must have rushed to Twitter and Facebook to tell all your friends, who must have been thrilled to hear it.
Ever alert math teachers would interrupt their classes with a question now: “Students, are there any other two-digit pairs of equivalent Fahrenheit ~ Celsius temperatures with reversed digits like that one?” What do you think, readers?
A seemingly cynical answer would be “What’s the difference?”, but I know that’s just your way of leading into something related: there’s an interesting way to find the difference between the two numbers in a reversed-digit pair.
a) Find the difference between the two individual digits: in the case of 82, 8 – 2 = 6.
b) Take what you just got and multiply it by 9: in this example, 6 x 9 = 54.
c) The result is the difference between the two two-digit numbers you started with: in this case, 82 – 28 = 54.
What does all this have to do with native plant photography? About as much as the difference between a pair of reversed-digit numbers like 88 and 88, but you know the refrain by now: variety is the species of life.
