Dot Product Error on Page 283 of Printed Book #292

On page 283, the dot product example seems incorrect. -30 + 5 = 35 should be fixed to read: AB = -3 * 10 + 5 \ 1 = -30 + 5 = 25 Right? Unless I'm missing an absolute value thingy there?

yup, this is an error, it should be -25. duplicate of this issue #276. closing.
