What Does 28 plus 47 Mean to You?

quip cardToday on Twitter, someone asked the question, “What happens in your brain when you add 28+47? Tell me your process – let me see how your brain works.”

Here were a few of the responses. Which one is closest to how you would answer the question?

a. Add the 7 and 8 remember 5; carry 1 and add to 2+4 equals 75

b. 20+40= 60; 8+7= 15; 60+10+5=75

c. 28+2 + 47 -2 = 30+ 45 = 75. (Basically take one number to the nearest multiple of 10 by adding the deficit from the second number)

d. I hit the little circle in the bottom of my phone and then open the calculator ap. I switch back and forth several times because I’m dyslexic and don’t trust myself to hold the numbers in my head the right way around. And it tells me it’s 75 which is more than 60 and less than 80.

e. Me: “Alexa, what is 28 + 47?”; Alexa: “I’m sorry, I did not understand the question.” Me: “Alexa, I said, what is 28 + 47?” Alexa: “Here’s Yellow by Coldplay.”

f. Because 28 = 4×7 , the 3nd Cosine of the 4rd logarithm of π squared divided by the binomial coefficient can be used find the 2st normal form of the bending moment of the right angled trilateral …75 I can’t make it any simpler.

g. When I was 28 I thought 47 was ancient. Now I only hope I make it to 75.

h. 8 unicorns + 7 unicorns = 15 unicorns; 4 kittens + 2 kittens = 6 kittens; 6 kittens + 1 unicorn = 7 unikittens; 7 conkittenated with 5 = 75 unikittens.

i. It’s a bit of an age gap… I forsee the relationship lasting at least 5 years. If it’s long distance the entire time? Probably less. But then again — ya might be soul mates.. what would I know?
