What is the Order of Operations
PEMDAS - parentheses, exponents, multiplication and/or division, addition and/or subtraction
100
-10 X 4 =
-40
100
-16 ÷ 4 =
-4
100
12 + -12 =
0 (opposites add up to 0)
100
0 - 5 =
-5
200
What is the Commutative Property?
The order you add or multiply 2 numbers doesn't matter, the answer is the same
200
5 X -6 =
-30
200
36 ÷ -6 =
-6
200
-5 + 3 =
-2
200
-6 - 3 =
-9
300
Write this expression in expanded notation - 8(x +y)
(8 * x) + (8 * y)
300
-8 X -9 =
72
300
-40 ÷ -5 =
8
300
-13 + -8 =
-21
300
-12 - (-12) =
0
400
Write this expression in expanded notation - -6(x-y)
(-6 * x) - (-6 * y)
400
1/2 X (-7/5) =
-7/10
400
2/3 ÷ 3/5 =
10/9 = 1 1/9
400
8 + -24
-16
400
7 - (-11) =
18
500
Write this expression in factored format - (6 * x) + (6 * y)
6(x+y)
500
-4/3 X 5/6 X -3/4 X 6/5 =
1
500
-3/4 ÷ -1/2
6/4 = 1 1/2
500
-7 + 8 + 10 + -8 + 7 + -10 =
0
500
-1/2 - 2/3 =
-3/6 - 4/6 = -7/6
