Here are the solutions for the addition problems on the worksheet. I have calculated each sum by adding the numbers in the ones, tens, and hundreds columns.
1.
51 + 169 + 61 = 281
2.
281 + 302 + 889 = 1,472
3.
840 + 808 + 905 = 2,553
4.
993 + 152 + 178 = 1,323
5.
183 + 657 + 46 = 886
6.
534 + 156 + 251 = 941
7.
91 + 647 + 386 = 1,124
8.
342 + 929 + 273 = 1,544
9.
561 + 213 + 166 = 940
10.
162 + 807 + 170 = 1,139
11.
475 + 277 + 888 = 1,640
12.
630 + 354 + 994 = 1,978
13.
922 + 609 + 950 = 2,481
14.
902 + 886 + 995 = 2,783
15.
601 + 191 + 435 = 1,227
16.
345 + 223 + 80 = 648
Final Answer:
1. 281
2. 1,472
3. 2,553
4. 1,323
5. 886
