This exercises will test how you are able to find the sum and difference of two vectors.

Solution of mathematics tasks is the best method to study this subject!

a + b = {; }

You have to press the "Next task" button to move to the next task.

Attention!!! After press "Next task" you can not return to previous exercise.

In the case of the plane problem the sum of vectors a = {x_{1}; y_{1}} and b = {x_{2}; y_{2}} can be found using the following formula:

a + b = {x_{1} + x_{2}; y_{1} + y_{2}}

In the case of the plane problem the difference of vectors a = {x_{1}; y_{1}} and b = {x_{2}; y_{2}} can be found using the following formula:

a - b = {x_{1} - x_{2}; y_{1} - y_{2}}
