Explanation
(a) 4,578 - 2,222 = 2,356. Subtract digit by digit: 8-2=6, 7-2=5, 5-2=3, 4-2=2. (b) 15,324 - 11,780 = 3,544. Align and subtract with borrowing where needed. (c) 5,423 - 423 = 5,000. Direct subtraction without borrowing. (d) 123 - 12 = 111. Align properly: 123 - 012 = 111. (e) 77,777 - 777 = 77,000. Align: 77,777 - 00777 = 77,000. (f) 826 - 752 = 74. Subtract with borrowing: 6-2=4, 12-5=7 (borrowed), 7-7=0.
