Name the property of addition that is illustrated. 7 + (6 + 8) = 7 + (8 + 6)?

Question

Hard time understanding this one, please explain.

Answer 1

This illustrates the fact that addition is commutative; that is, for any numbers a and b, a + b = b + a.

In going from 7 + (6 + 8), we just have to switch 6 and 8 to get 7 + (8 + 6), so this is the appropriate property.

Answer: Commutativity.

Answer 2

The property of commutativity--a + b = b + a. The only thing changing from the left side of the equation to the right is what is in the parentheses, so the fact that they're equal implies that (6 + 8) = (8 + 6). This is the commutative property--it doesn't matter which order you write them in, the sum is the same. (Contrast this with subtraction--is (6 - 8) the same as (8 - 6)?)

Answer 3

It is the associative property. When adding a series of numbers (more than two), it does not matter how you group them when adding- you still get the same answer.

In simpler terms, it doesn't matter which numbers I add together first, I'll end up with the same answer.

(Many people mentioned the commutative property- that's when you change the order of the numbers, not the grouping of the numbers.)

Answer 4

the prorerty of equal addition which means 2+(4+6)=12 and 6+(4+2)=12 and its equal im really sorry if i cant help

Answer 5

It's the Associative property od Addition, I think. I just learned in school. That's where you can put the numbers in parenthesis.

Answer 6

commutative. it means that it is still mathmatically equal when the figuers are switched but there are some limits such as addition and multiplication

Answer 7

Communative: because only the things in the brackets have changed order.

Answer 8

a+(b+c)= a+(c+a)
u know that addition is commutative.so when it is added in any way it will give the same answer
