{\large {\bf  Homework: Studying for Test 2  
}}
\end{center}

(1) You MUST get together, in person, with someone else from the class for at least 1 hour. Maybe have a Studying Sleepover the night before the test. 

(2) Bring your Test 1 to class and give it to me. I'd like to compare the kind of mistakes you make on each test. 



(3) Words: Exponent. Endless loop. Mixed number. Prime. Factor. Prime factorization. Theorem. Quod erat demonstrandum.  Ramanujan. Ramayana. 

Topics: Exponents. Square roots.  $10^2, 10^{-1}, 10^0,  10^2\cdot 10^3 = 10^5$. Word problems with irrelevant information. Prime numbers. Factors. Prime factorization.  Multiplying fractions. Dividing fractions. Converting between mixed numbers and fractions. Writing letters  and emails. 

Python: Know these commands. You can cut and paste this code into CodaBrainy and run it if you like, to see what it does. 
\begin{verbatim}
#This is just a comment   #Output: Nothing. It just adds some words to your code. 
import matplotlib.pyplot as plt  			 #Output: Nothing. It just allows you do do plots later. 
print("Here is something  to print out.") #Output: Here is something to print out.
ages = [11, 12, 13, 15]   		#Output: Nothing. It just creates a list to use later if you want. 
names=["Sam", "Judy", "Faith", "Henry"] #Output: Nothing. It just creates a list to use later.
weights = [80, 100, 102, 93]  	 #Output: Nothing. It just creates a list to use later.
print(ages) 																	#Output: [12, 13, 12, 14]
print(names) 																#Output: ['Sam', 'Judy', 'Faith', 'Henry']
me = 62  	  	#Nothing.  It just creates a variable label (me) to use later if you want.
print (me)  																	#Output:  62
print(me/2) 		 	#Output: 31.0  (so you can use Python as a calculator if you want)
plt.plot(ages,weights,color="red", linestyle="dotted") #Output:Nothing.It gets a graph ready.
plt.show()		 	#Output:  A graph showing a dotted red line of ages and weights.
