today in class we started a new unit (as clearly seen above) integers! instead of strictly adding and subtracting like we did last year, we are also multiplying and dividing. today in class we did a review on adding and subtracting integers.


some examples of integers are

positive integers

negative integers

and zero


there are also pictorial representations of integers.


one of the ways Harbeck represented integers was with money, such as:

you have 15 dollars and you owe 10 after paying you have 5

(15) + (-10) = (5)

and you can represent it on a number line

MR. Harbeck also showed us how if you remove the brackets it become grade two math.
we also have homework
part B:write an integer to represent each of the following
1. Losing 10$: (10-)
2. Finding 100$: (+100)
part D: write the next three integers in the pattern
1. +2, +4, +6 : +8, +10, +12
2. -9, -5, -3: -3, -5, -9
part F: rearrange integers into ascending numerical order.
1. +5, +7, +9, -3:-3, +5, +7, +9
2.+5, -5, +3, -3: -5, -3, +3, +5
Braden, so should write notes for next class, its your turn!

    You have a very nice post except you might want to add in some capitals when needed but other than that good job!
