Answer:

Associative propertry of addition.

Step-by-step explanation:

The associative property of addition states that:

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

It states that we can add numbers regardless of the groups. The sum does not change  irrespective of how the addends are grouped.

We are given the expression:

r + (h + t)

It can be written as:

(r+h) + t

It can also be written as:

r + (h+t) = (r+t) + h = (h+t)+r = h + (t+r)

Whatever maybe the arrangement of r, h and t, their sum will always be equal. We can regroup them in many ways but the sum remains the same.
