Lmao! As a math geek who can't manage simple arithmatic, I whole-heartedly approve!
as a recent phd graduate of mathematics, I get asked these kinds of questions all the time... and I still don't know what 11 x 13 is!!
11 x 13? Plenny!
My resopnse would be "No 1 cares. I've said this be4. This is the 3rd time."
A friend of mine once said "I majored in Mathematics, not Arithmetic!".
143. Sheesh, it's easy multiplying by eleven; just multiply by ten and add the original.
Wow. Why is it that I have never heard it put that simply before? All my years of school (including graduate school) and I get the best method from a comment on a comic. :-)
What base? Decimal or hexadecimal? Can I use a calculator?
I am not a mathematician, but I sure can do arithmetic. I love this comic.
That's because Sonic Lover is a Alpha Geek.
Seriously guys?
Multiplying by eleven is easy by head, no matter what the second number is.
For you!
Well, I honestly can't add 130 + 13. You know 13 is a very scary looking number. (It is, trust me!!) heh
You guys, 11x13 = 12^2-1 = easy.
A fellow mathematician once told me: There are three kinds of mathematicians: those who can count and those who can't.
Given that, how do you expect us to do higher arithmetic? There's a reason I like algebra. X times Y is always XY, but who can figure out what 11 and 13 make?
Wait. Doesn't that make eight kinds of mathematicians?
11 times 13 is 1113 by bmonk logic,
Who said they were numbers?
For mathematicians.. numbers don't even exist.. they might as well be letters or drawings..
he could have said: it gives up kittens! makes no difference
wow..i cant iterate how much i can relate to this comic. i get an entire formula worked out, then in the end i do 2+3=6 or something like that
SHEESH YOU PEOPLE! 143!
Also what is it with the algebra?? this is just simple multiplying!!!
And also, PLEASE, SOMEONE TELL ME, what is the difference between Maths and arithmatic?
plz reply!
How to easily calculate 11*13
if x= 10
then, 11= x+1, 13= x+3
(x+1)(x+3)=(x^2+4x+3)
(10^2+4*10+3)=143
That was easy, wasn't it?
You guys missed an intro step in your High School algebra classes. You all know how to do (x+1)(x+3)
Well what about (10+1)(10+3) or 13(10+1)
Both of those are really simple to do. Come on guys.
There's a WAYYY easier way to multiply by 11:
Take the two digits of the multiplicand, add them together, and put the result in the middle!
13 x 11 ---> 1 + 3 = 4
therefore 1"4"3
works with any... 11 x 53 = 583
11 x 72 = 792
(if the sum is 10 or more, carry the one)
11 x 76 = 836 (not 7136, obviously)
See, this is why I always transform an arithmetic problem into an algebra problem, like all the comments have described. Mathematicians don't do arithmetic!
