I missed the first lecture of my physics class and need help answering these simple questions. They have to do with adding and subtraction and multiplying unit vectiors. What do they mean by direction, this is in degrees?

Also, I am not sure if this is possible but a diagram would be very helpful.

## Homework Statement

Suppose B = -7i + 2j and G=6i - 4j. Find the magnitude and direction of:

a.) B + G

b.) B - G

c.) 3B

Thank you
