5x3=3x ?
5
Is this an example of the associative property? (8 + 9) + 4 = 8 + (9 + 4)
Yes, the numbers are the same on both sides and the parentheses moved
True or false: 3(4+b)=12+3b
True
13x1=13 is which Identity Property?
Identity property of multiplicatoin
(3+2)+7=3+(2+7)
Associative Property of Addition
True or False: If you know 4x6, you know 6x4.
True
(4+5)+9= 4 +(a+9) a=?
5
5(b+7)=5b+?
35
Give and example of the Identity property of addition.
A+0=A
19 + 0 = 19
Identity Property of Addition
4+6=6+4 is which commutative property
Commutative property of addition
Is this the associative property? 3+(2+1)=3+(1+2)
No, this is the commutative property
Explain the Distributive Property
Multiply the outside term times each of the inside terms.
Is 5x0=0 the identity property?
No, it is the zero property.
24 - 12y = 12(2 - y)
Distributive property
Give an example of the commutative property of multiplication.
ab=ba
9+3+7 What should you add first to make the problem easier?
9+(3+7)=10+9=19 😀
Give an example of the distributive property.
3(2+5)=6+15
How do the identity property of addition differ from the identity property of multiplication?
For addition you add 0; for multiplication you times 1.
(8x2)x6=6x(8x2)
Commutative Property of Multiplication
Jones goes to the store to get a 16x20 filter. The store clerk gives him a 20x16 filter. Why is this the correct filter?
You can change the order of the factors by flipping the filter 90°.
Explain why the movement of the parentheses does not change the answer on the right and left side of the equal sign.
The parentheses group numbers together, which means that these numbers are added first. The order in which all of the numbers are added together does not matter, because you still get the same total.
Distribute: 3(b+10)
3b+30
Define the Identity property.
Any number times 1 or plus 0 is that number; it stays the same.
2(3 + 6) = (2*3) + (2 * 6)
Distributive Property
