Commutative property of multiplication/addition
What does |-5| mean?
the absolute value of -5 is how far away -5 is from zero.
Graph -15, -10, -5, 0, 5, 10, 15
see student work
Solve the equation be sure to show all your steps
7 + x = 19
x = 19 - 7
x = 12
Give an example of an integer
any negative/positive whole number or zero
Which property says that the sum or product will not be affected if we group products or addends differently?
Associative property or multiplication/addition
What is the absolute value of -12?
12
Compare:
-3 ___ -1
<
Solve the equation be sure to show all your steps
7 + 5 + x + 2 + 6 = 30
24 + x = 30
x = 30 - 24
x = 6
What kind of number is a percent?
rational
Give an example of the zero property of multiplication.
Any number times zero will equal zero.
4 x 0 = 0
What is the absolute value of 11?

Solve the equation be sure to show all your steps
6p = 84
p = 84/6
p = 14
Is a whole number a counting number? Explain
No, the whole number box won't fit in the counting number box.
Illustrate the Identity property of addition.
any number plus zero equals that number
ex: 5 + 0 = 5
100 - 365
- 265
Arrange from least to greatest:
-5, 3, -2, 1
-5, -2, 1, 3
Solve the equation using inverse operations. Be sure to show all the steps
39/x=13
39=13x
x=39/13
x=3
Using braces and digits write the set of whole numbers.
{0, 1, 2, 3...}
Illustrate the identity property of multiplication.
any number times one equals that number
ex: 6 x 1 = 6
36 - 87
- 51
|n| = 10

When you solve the equation 15 - i = 24
What will the next step look like?
15 = 24 + i
