Oups yes it is imbecile. Sorry i haven’t seen the article on the imaginary numbers. Thanks

I’m not good at math and my few basis are old so I’m happy to find here a way to understand some scientific articles in deep (for example what a convolution is) . But here i have problems with the complex numbers: what does the i become when calculating the magnitude? Why don’t you develop the formula that gives -7+24i in the multiplication section? Can’t guess i2=-1 (got it by other means)?
Sorry if it seems imbecile, just think you’d develop

Thanks John, hope the analogy works for them!

I really like the comparison of the "implied addition" used in mixed fractions with the explicit addition used in the a + bi form of complex numbers. My beginning algebra students often balk at those mysterious complex numbers and having a real and an imaginary part can add to the mystery and that is a nice tie-in to something they find simple and familiar. I can feel myself "hand waving" past this idea when I introduce it and I think this gives me something I can explain with more assurance. Thanks for the idea!
