I was reading a book about special relativity when I saw this blok: AEscreenshot.jpg (1) $\displaystyle s^2 = \Delta x_1^2 + \Delta x_2^2 + \Delta x_3^2$ My problem is the substitution of (2a). I don't understand how this substitution looks like or how it works. This question might be stupid or in the wrong forum, but I really need help.
