Summing and subtracting vectors

Now that you have the poker and roulette winnings nicely as a named vector, you can start doing some data science magic.

You want to find out the following type of information:

How much has been your overall profit or loss per day of the week?
Have you lost money over the week in total?
Are you winning/losing money on poker or on roulette?

You'll have to do arithmetic calculations on vectors to solve these problems. Remember that this happens element-wise; the following three statements are completely equivalent:

c(1, 2, 3) + c(4, 5, 6)
c(1 + 4, 2 + 5, 3 + 6)
c(5, 7, 9)

Exercise instructions

Take the element-wise sum of the variables A_vector and B_vector and it assign to total_vector. The result should be a vector.
Inspect the result by printing total_vector to the console.
Do the same thing, but this time subtract B_vector from A_vector and assign the result to diff_vector.
Finally, print diff_vector to the console as well.

Hands-on interactive exercise

Have a go at this exercise by completing this sample code.

# A_vector and B_vector have already been defined for you
A_vector <- c(1, 2, 3)
B_vector <- c(4, 5, 6)

# Take the sum of A_vector and B_vector: total_vector

  
# Print total_vector


# Calculate the difference between A_vector and B_vector: diff_vector


# Print diff_vector
