# + plus == addition
# - minus == subtraction
# / slash == division
# * asterik == multiplication
# % percent == Mostly that's just how the designers chose to use that symbol. In normal writing you are correct to 
# read it as a "percent." In programming this calculation is typicaly done with simple division and the / operator. 
# The % modulus is a different operation that just happens to use the % symbol.
# < less-than
# > greater-than
# <= less-than-equal
# >= greater-than-equal
# == equal-to

# Python always uses the orders of operations PEMDAS
