Question

Does anybody know how to explain the distributive property and communitive property I’m in 7th grade I’m confused

Answer 1

2(a+3b)

The distributive property applies here. You can't combine the a or the b with anything else until you get them outside the parentheses. You have to "distribute" the multiplication by two across the a and b.
You get 2a + 6b.

a+b+c = a + c + b = c + a + b
This is an example of the commutative property. You can change ("commute") the order in which you add things together.
if you have a quarter a dime and a nickel, you can start with 25, add 10 to get 30, then add 5 to get 40.
Or if you want, you can start with the nickel, then the dime and finally the nickel. You get 5, then 15, then 40.
The order of addition doesn't matter as long as everybody gets added in. The commutative property also works for multiplication.
2 × 3 × 4 = 24
That's 2 groups of 3 = 6, then 4 groups of 6 = 24.
3 × 4 × 2 = 24
That's 3 groups of 4 = 12, then 2 groups of 12 = 24.
Again, the order of multiplication doesn't matter.

Does this help??
