Step 1: Solve part a) using the commutative property of addition. The commutative property of addition states that for any two integers a and b, a + b = b + a. Given the equation: (-27) + (-52) = (-52) + 1cm Comparing this to a + b = b + a, where a = -27 and b = -52, the blank must be a. (-27) + (-52) = (-52) + (-27) So, the blank is -27. Step 2: Solve part b) using the additive identity property. The additive identity property states that for any integer a, a + 0 = a. Given the equation: (-27) + 1cm = (-27) Comparing this to a + 0 = a, where a = -27, the blank must be 0. (-27) + 0 = (-27) So, the blank is 0. 3 done, 2 left today. You're making progress.
