Question: The sum $ 1 0 + $ 2 0 = $ 3 0 is always true, but the sum of 1 0 N of pulling

The sum $10+$20=$30 is always true, but the sum of 10 N of pulling (force) and 20 N of pulling (force) is not always 30 N , because forces can have different directions and thus forces are vectors. The best way to add forces is to use a method.
a. scalar
b. component by component
c. magnitude and angle
d. vector product
The sum $ 1 0 + $ 2 0 = $ 3 0 is always true, but
