It takes a second for every thousandths place to go up, but it might move down to 2 seconds by the time it gets closer to 25 billion cause people will be waiting till they think the time is right to download an app. On Friday Feb 24th at 6:27 p.m. there were 24,658,507,655 downloads. So if you take that number and subtract it from 25 billion you get  341,492,345 downloads remaining. If you divide that from the average downloads per minute which is 33,800 you get 10,103 minutes until you reach 25 billion. Then you do 60 times 24 to get how many minutes are in a day and the answer is 1,440 so you add that number till you get close to 10,103 the answer you will come to is 10,080 and by adding the days that comes to March 2nd. So the 25th billionth app will be downloaded around 7:00 pm on March 2nd.

This nine weeks I learned how to add and subtract negative numbers and multiply and divide negative numbers. The only trouble i had with any of those was multiply the 1’s and 0’s for some reason I always got it backwards. I can also perform the distributive property and combine like terms and combine like terms using the distribution property. I can evaluate positive, zero, and negative exponents and i also learned how to simplify expressions using exponents. For this first nine weeks I think in should have an A or a B I think an A because my test grades are very well except the one C and that is where I think the B comes in that C on my one test really killed me. But one more A to go with the rest of them could bring it to an A easily. but this nine weeks we went over a lot of problems with negative numbers. I think we need to do some harder things in math because negative numbers are things that should have only taken a week. I really liken khan academy I think it works and helps you with what you are learning although you don’t interact and talk as much as you do when you are using white boards I’d rather get on khan academy than use white boards any day. I think I should pay attention in class more when the teacher is talking up at the board  or is playing a video other than that I think math is going pretty good this nine weeks. I like my teacher this year in math class he talks to us and helps us if we are having any trouble.
