PYTHON CODE:

- print("Buddhist code.")
- x = 4
- item=1
- while x<6:
- print("Glory to God in the highest!",item)
- item = item +1
- print ("The End.")

*Steps in solving word problems:*1. Figure out what the question is and what kind of number is supposed to be the answer. 2. Figure out which numbers in the question are relevant--- some numbers might well be irrelevant to getting to the answer. 3. Figure out what techniques you are going to need, e.g., addition, division, Python coding, looking up something on the Internet.
