Karen, September 9th

Hello there! Well, today we started off by taking Daily quiz #4 just to practice our use of exponents. After that we went over problem #89 on the homework from Tuesday night and realized we used a fraction symbol instead of division which did in the end determine our final answer. This is what the book wanted us to do originally:

(V × .5485 - 4850) ÷ 1000 × 31.44

Which is working from left to right.

And this is what we made a mistake on in class:

(v × .5485 - 4850)

_______________

1000 × 31.44

Which is using the fraction symbol in replacement for the division symbol.

We were thinking that it is the same exact thing but when you work from left to right like the book wanted us to, we divide 5000 by 1000 and THEN multiply it by 31.44.

But the other way we did two separate equations and THEN divided them by each other.

Next off, we went over Daily Quiz #3 from yesturday.

One main point we covered was that if you are adding two numbers with the same symbol,

you add the absolute values of each number and then on your final answer you return the symbol you were originally working with. here is an example:

5+8=

|5| + |8| = 3

But if you are adding with two numbers of different symbols,

you take the absolute value of the bigger number and subtract it from the smaller number. Here is an example of this type of problem:

-5 + 6=

|-5| + |6| = 11<---- this is where you return the original symbol to ultimately get: -11

And that's practically all we went over hope you enjoyed pretty colors! =]

For the next scribe I think Tyler should do it.
