Explanation
(a) 238 + 367 = 605. Add with proper alignment: 8+7=15 (write 5, carry 1), 3+6+1=10 (write 0, carry 1), 2+3+1=6. (b) 1,234 + 12,345 = 13,579. Align properly and add digit by digit from right to left. (c) 12 + 123 = 135. Align: 012 + 123 = 135. (d) 46,120 + 12,890 = 59,010. Add with proper alignment. (e) 878 + 8,789 = 9,667. Align and add: 8+9=17, 7+8+1=16, 8+7+1=16, 0+8+1=9. (f) 1,749 + 17,490 = 19,239. Add with proper alignment.
