Integers: Scribe blog review
Yesterday we learned basic information about integers.We learned that you don't add when dealing with integers but you combine, we learned how to make sentences out of the math questions, how to put them in a number line, and we learned that:(Basic how to add integers)
Have = +
Owe = -
Today was a follow up of that ^. Today we learned:
Training wheels be gone, welcome to grade 8! ;) :
When writing a integers question or answering one you don't need to put brackets around a positive number.
(-8) + 2 is the same thing as (-8) + (+2)
Instead of writing it as:
Owe 8 and have 2 = Owe 6
You have to write it as:
Owe 8 have 2 = Owe 6
If this was applied nothing will change. It's just a way of not wasting time and to have a more "advanced"approach towards the question. This is called standard form.
You can always just re-write the question with the "training wheels" (brackets). This is for the beginners who need a bit more time to develop. This phase is not needed if you understand the concept.
Note: Remember that if a number is in a bracket without an operation it is considered as a "have"/positive.
Warm up questions we had for today:
(-10) + (6) = (-4)
Owe 10 and have 6 = owe 4
(-8) + 2 = -6
Owe 8 have 2 = owe 6
-8 + 7 =-1
Owe 8 have 7 = owe 1
