# You can perform mathematical operations on variables
# Imagine we have three groups with different totals of students
group1 = 100
group2 = 50
group3 = 75
# You can get the total of all groups through addition
total = group1 + group2 + group3
print("The total is: " + str(total))
# Note that str(number) gives a string variables from a number
# You can do the same with other operators
half = total / 2
print("Half of the total is: " + str(half))
double = total * 2
print("Double of the total is: " + str(double))
# Below, try to print out the value of the total students if one of the groups dropped out (subtraction)
#redTotal = ?
#print("The reduced total is: " + str(redTotal))
