#we say true or false to say yeah or no
# string is plain text

print(round(4.2))
#this round the number to the nearest whole number
from math import *
#this will tell python to go grab more maths functions
print(floor(3.7))
#this will grab the lowest number so in the xample obove it will print 3 and chop off .7
print(ceil(3.7))
# this will do the opposite to floor and will round the number up.
