little help?

• Alena says:

i 8 sum pi

• Beepage says:

Thanx. Now I want pi(e)

2. Amy says:

LOL yessssssssssssssssssss

3. kacyface says:

“i 8 sum pi”

• Alex says:

-i 8 sum pi as well.

4. Jason says:

Actually, wouldn’t it be “1 (i.e., one) 8 sum pi”? Not being picky, but you know.

• Cathmor says:

The square root of -1 techinically doesn’t exist, so it is commonly referred to by the imaginary number ‘i’, so math nerds can still calculate with it :-)

• Daniel says:

You beat me to it! Hah.

• Daniel says:

No, the square root of -1 is an imaginary number, which is indicated by “i”.

• Jeremy says:

• Jeremy says:

The square root of negative one is a number in the non-real number system. Such complex numbers are shown as “i”. Eg. 2 x squ. root of -1 = 2i, etc. Don’t correct things if you don’t fully know the subject. :P

• Jason says:

Sweet! Thanks for the clarification, math nerds.

5. JoeS says:

Doesn’t work for Greek students: I ate Sigma Pie

For some of us math nerds, √-1 = j

So… j 8 sum pi

Who is j?

• Coleslaw says:

Yeah. I was going to say the same thing. We – for EE people it’s j.

7. Mack says:

Argh ! just WHO ate Sigma Pi ??? ( Fraternity )
the little sisters of Sigma Pi ?? tsk tsk

8. Wyeth says:

I had to ask my college-age, electrical-engineering-major son to translate for me.

I get it, now.

9. anonymous moose says:

as an actual math professor, I read this “I ate Sigma Pie”, and needed the comments to figure out what the Sigma should be read as to make this work. No mathematician calls this “sum” when it’s written like this. If it has start and end indices, it would be a different story (and even then, we usually call it “sigma” anyway).

• John says:

Engineers know it means Sum.
