let us make a math game. The user will be asked a simple math problem in the first round. For example, to add two single digit numbers. If the user gets this correct, they will be given points and asked a more difficult math problem in round 2, such as adding a pair of two digit numbers. They will receive more points and be asked more difficult questions in the following round for every correct answer. Every incorrect answer will be followed by a simpler question. There should be a total of 4 rounds. At the end of 4 rounds, the code should print the final score. This will be a little challenging, so it is the only problem this week. You may need case statements and the random method.

Here we discus about the program. In this program we really focused on user inputs and if statements. This easily allowed us to be able to go in and make the program run differently each time no matter how the user enter the data. It was a pretty difficult assignment though it took me quite a bit of time understanding the basics of how the if statements worked. Im really glad we went through git and learned how to use the basics of it. Git allowed me to be able to look in at the master code to figure out things when I was stuck making the program.
