The answer is the Associative Property of addition. Associative property of real numbers is related to how we use the parenthesis in the expression while adding or multiplying, we always get the same answer. like a + b + c = (a + b) + c = a + (b + c) The given equation is 4.5 + 9.8 +1.5 + 3.2 = (4.5 + 9.8) + (1.5 + 3.2) = (4.5 + 1.5) + (9.8 + 3.2)
I’m learning this to lol I think the answer is c because the absolute value is always positive right ? And the opposite of -0.89 would be positive 0.89 !
