Ms. Vallejo bought a Camera for $1,249 and some extra materials for $80 each can be represented with "M". If she paid a total of $1809, how many extra materials were purchased?
Rate 80 m
Constant 1,249
Total 1809
Formula Rate + Constant= Total
Equation 80m+1249=1809
M= 7 extra material was purchased

Name all the rules needed to solve the solving problem?
1. -30 + (-40)=
2. -40 - 20=
3. 75-80=
4. 132+(-423)
1. add and keep the sign. = -70
2. KAO & add and keep the sign = -60
3. KAO & subtract and take the largest absolute value = -5
4. Subtract and take the largest absolute value= -291
What is a commutative property?
Rewrite the problem using commutative property and solve the problem
For example= 8 +1 = 1+8
9 = 9
3+5 =
8-3 =
(3)(2)=
10/ 5 =
Which two operation can you use the commutative property ?
Commutative property is when you change the order around and get the same product
3+5 = 5+ 3
8 = 8
8-3 = 3-8
5 = - 5
(3)(2)= (2)(3)
6 = 6
10/ 5 = 5/10
2 = .5
Addition and multiplication can be used with the commutative property
4.6-7.34-(-8.45)
5.71
