Sagot :

When we are adding three terms, the order of the terms being added does not change the final result.

For example, in the sum 15 + 5 + 7, if we add first the 15 and 5, we have:

[tex](15+5)+7=20+7=27[/tex]

And if we add first the 5 and 7, we have:

[tex]15+(5+7)=15+12=27[/tex]

This property is known as the associative property of addition.

Correct option: fourth one.
