Zero Pair-A pair of numbers where one number is postive and the other is negative and when added, they equal zero.
Examples:
+6 -6 -10 +10 19 -19
-16 +16 -11 +11 +14 -14 63 -63
Integers from Grade 7
Positive (+) means you have
Negative (-) means you owe
( ) Brackets are like training wheels
Standard Form of Integers is +4-4
Pure Standard Form is 4-4
Chapter 2: Multiplying Integers
(+3)x(+8)(+3)(+8)-If the brackers are touching, it means you have to multiply
3(+8)
(+8)+(+8)+(+8)-You can use repeated addition
Chapter 3: Dividing Integers
Partative Division-Dividing by groups
6 divided by 2
Quotative Division-Sharing with groups
-6 divided by 2
Multiplicative Inverse can help solve 6 divided by -2 because if you solve the question and find the answer, you just have to switch the quotient with whats being divided.
Sign Rule-If they have the same sign or an even number of signs, its positive
If there are two different signs or a odd number of signs, its negative
Chapter 4:Order of Operations with Integers
(+5) x (-3) + (-6) divided by (+3)
(+5) x (-3) + [(-6 divided by (+3)]
(+5) x (-3) + -2
[(+5) x (-3)] + -2
-15 + -2
-17
