Question

Which expression is equal to a + (b + c)?

(a + b) + c
(a + b) ⋅ c
a + bc
b + ac

Answer 1

`\huge{\boxed{(a+b)+c}}`

For example,
`2+(3+4)=2+7=9`.

If we group the terms differently, it doesn't matter.
`(2+3)+4=5+4=9`

This is called the associative property of addition. As long as you still have all of the terms, and there are no other operations (subtraction, multiplication, etc.), the final answer will remain the same no matter how the terms are grouped.

Answer 2

The correct option is (a+b)+c

Explanation:

The correct option is (a+b)+c

According to the Associative property for Addition:

a+(b+c)=(a+b)+c

The associative property states that you can add or multiply regardless of how the numbers are grouped.

.If you are adding or multiplying it does not matter where you put parenthesis.

Thus the correct option is A....
