Suppose you'd like to count how many calories you've burned from exercise. You do
4 kinds of exercise: yoga, walking, sprinting, and volleyball. Every day in January, you record how many minutes of each kind of exercise you did that day. Those data are in a table calledexercise.csv
How do I sum the 4 different sports, as a sum of the row would also include the 'Day (in January) column?
