The Scalar product of =6.0 + 4.0 - 2.0 and =5.0 - 6.0 - 3.0 is 12. An easy way to reach this solution is to stack the two equations on top of one another and multiply top to bottom, while at the same time putting plus signs in between our coordinates. Following these directions, we get an equation that looks like this: (6.0*5.0)+(4.0*-6.0)+(-2.0*-3.0) this can be simplified to 30-24+6 which, following the order of operations and solving left to right, gives us an answer of 12.
