How do you calculate the magnitude of the dot product (vectors)?

Vectors:

-3 3
2 . 2
1 -1

If you wanted to have the dot product in absolute value, how would you proceed?
The solution without absolute values ​​is -6. Would you then change -6 to +6, or would you change the numbers with negative signs to positive ones in the calculation? For example, 3 x 3 + 2 x 2 + 1 x 1 = 14.
Which of the two paths is correct?

Hello,

the scalar product is a number. The amount of this number is their distance from the zero.

In the case of positive figures, the amount and the number agree; in the case of negative figures, the amount corresponds to the positive number; Amount of -41 is then simply 41.

Best regards,

Willy
