 # Answer to Homework Question
 I hope to learn how to perform MATLAB functions more easily.
 
+#A_66
+```MATLAB
+A_66=zeros(6:6);
+for i=1:6;
+    j=1:6;
+    A_66(i,j)=i*j;
+end
+Average = mean(A_66(:))
+Standard_Deviation = std(A_66(:))
+

 #Problem 4
 ```MATLAB
 data=dlmread('US_energy_by_sector.csv',',',2,0);
