Explain please. Refer to 6 to answer 7.

Given the following two 32-bit binary unsigned numbers A and B, find the logs expression of the carry flag when A and B are added. The result is R. A = a_31 a_30 a_29 ...a_2 a_1a_0 B= b_31 b_30 b_29 ...b_2b_1b_0 R = r_31r_30r_29...r_2r_lr_0 Find the logic expression of the carry flag when B is subtracted from A, where A and B have the same format as Question 6
