How do you add 2 vectors and subtract a third using the Parallelogram Rule?

To apply the parallelogram rule, you have to break up the addition and subtraction into groups of 2 vectors at a time
Instead of subtracting vector C, you can add the negative of vector C

1. When you flip C, you rotate it about its tail, and you get the vector -C
1. The parallelogram rule only works for two vectors at a time
1. Line up the tails of A and B and make a parallelogram from those two sides
1. Now you have one vector from A+B, and you add that to the -C vector
1. Now you have one vector from A+B, and you add that to the -C vector
2. Line up the tail of the A+B vector with the tail of the -C vector, and then make a parallelogram

Given vectors A, B, and C, find the total vector given by A + B - C using the Parallelogram Rule for vector addition.
