# Create a numpy array arr with values 6, 9, 12, 1, 4, 5 in it with data type int

# Create a numpy array matrix arr2 of ones with dimensions 5 by 2 of data type float

# Create a numpy array vector arr3 of numbers from 1 to 20 of data type int

# Create a numpy array vector arr4 with 30 numbers evenly spaced between 10 and 20 of data type float

# Multiply each element in arr by 2 and save it to arr5

# Divide each element in arr5 by 2 and save it to arr6, confirm arr6 == arr

# Create two random array matrixes arr7, and arr8 of size 3 by 2 where each number is between 0 and 100 as ints

# Add matrixes arr7 and arr8 element wise together and save to arr9

# Sort arr9 in ascending order and store in arr10

# Concatenate arr7 and arr8 along the columns and store in arr11

# Reshape arr10 to be 2 by 3 and store in arr12

# Get all numbers in arr10 that are greater than 50 and less than 75 and store in arr13

# Get the sum of all numbers in arr13 and store in x
