-6 - (-4)= -2
-10+6= -4
6-7+2= 1
14-(-3)= 4
-3-(-7)= 4
-3-7= - 10
3+7=10
-3+7=4
Chapter 2- Multiplying Integers
Examples for todays class
(+2)(+3).... 2 groups of +(3) = +6
(-2)(-3)...... remove -2 groups of -3 = +6
(+2)(-3)...... 2 groups of (-3) = -6
(-2)(+3)....... remove -2 groups of (+3)
Chapter 3- Dividing Integers
Even : When you have a even number of negative factors your product is positive.
(-6) / (-2)
Quotative Division - sharing a certain number between a given value.
ex.
(-6) / 2 = -3
Chapter 4: order of operations
(+6) x (-2) + (-6) ÷ (+2)= +15 (how to get answer)
(-6) ÷ (+2) = -3
[(+6) x (-2)] = (-3)
-12 + (-3) = -15
order :
1. brackets (square brackets)
2. division
3.multiplication
4.addition
5. subtraction.
Chapter 3- Dividing Integers
Even : When you have a even number of negative factors your product is positive.
Odd :When you have a odd number of negative factors your product is negative.
Partitive Division : when you use groups to find your quotient.
6 \ 2 =3
6 \ 2 =3
(-6) / (-2)
Quotative Division - sharing a certain number between a given value.
ex.
(-6) / 2 = -3
Sign Rule
In a division question if there is an even amount or no (-) the answer will be a positive
In a division question if there is a odd amount of (-) the answer will be negative
