My Christmas wish is to get an Xbox One from my parents. That’s not much of a wish but I suppose for a real wish, I hope to have fun with friends and family and get what I want. I would also like to win WSAZ’s.
Merry Christmas, from Nate Santiago.
According to the data we got yesterday, we did the math, and got that you should start downloading apps on March 5th at aproximately 6:24 am. We got this by using the pictures shown and found out that it was roughly 30,000-40,000 downloads per minute. Using that math we found out that it would take 10 days and 12 hours and since they are 3 hours ahead of us, we figured that it would be about 6:24 on March 5th when you should start downloading apps to maximize your chances of winning the contest of being the 25 billionth download.
Overall I like how math class is done right now. If I were to add some suggestions I would say to make it more fun. You could do more games or activities.
In the first nine weeks I have learned a lot of things.
One specific thing is adding and subtracting integers. It is adding and subtracting negative numbers. For example
-32 + 53= 21
I can do this because I got a 100% on the test. And I am practiced on khan academy
Another thing is multiplying and dividing Integers. For example
-5 x 3= -15
I can do this because I also got an A on this test
We also learned how to preform the distributive property. For example
16 + 8 is the same as 8 x (2+1)
I had some trouble with this but eventually I got it as shown on my test score and on Khan Academy
It is easier to combine like terms with distribution. For example
-11 – 3(-2n + 9) = 6n +-2
My grades also support this
I can evaluate positive, zero, and negative exponents. For example
4^-3 = 1/64
My grades on livegrades show that I understand this.
The last thing we did was simplify expressions using exponents. For example
7 + 6(y+1) = 6y + 13
Overall I would give myself an A because I understand all of the things we did and I got an A on all of the tests.
So, I will be writing about exponents today. Exponents are pretty simple, for example, what is 5^2 would simply be 5 * 5 which would make 25. Pretty easy right? Well here’s where it gets complicated in the negative exponents. But let me show you something, 9^-2 seems pretty hard but all you do is put a 1/ over the answer to the exponent but positive, your answer would be 1/81. If you are doing fraction like 3/4^-2. You simply just flip the numbers, making it 4/3 and the act as if the exponent is positive, resulting in 16/9. Also, remember that if anything has an exponent of ^1 is is just the original number. However, if it is an exponent of ^0 remember that it is ALWAYS 1. And that is exponents.
My number is 79. I started off by finding the two closest integers, which are 8 and 9. I then subtracted those square roots, which are 64 and 81 to get 17. the middle of 17 is 8.5 so I added 8.5 to 64, getting 72.5. The middle of 8 and 9 is 8.5 so it leads to believe that the square root of 72.5 is 8.5. Now back to 79, it’s closer to 81 than 72.5 so I knew that it would either be 8.6, 8.7, 8.8, or 8.9. I couldn’t decide whether it was one other other so i went with about 8.86. In conclusion, I estimate that the square root of 79 is about 8.86.
This is my first post and I want to talk about multiplying/dividing negative numbers and adding/subtracting negative numbers. One rule to multiplying and dividing negative numbers is that if there is only one negative number in it, the answer will be negative, but if there is two than the answer will be positive. For example, -25*3=-75 or -5*-5=-25
