Which of the following equation represents the associative property w.r.t addition?

1 + (4 + 3) = (1 + 4) + 3

5(a + b) = 5a + 5b

a + 0 = 0 + a = a

None of these

The associative property w.r.t addition states that the order in which we add numbers does not change the result.

The correct equation is:

1 + (4 + 3) = (1 + 4) + 3

This equation represents the associative property of addition.
