Answer key
Compare each answer with the same question on the worksheet.
1.48 − 15 =33
2.14 − 12 =2
3.98 − 88 =10
4.67 − 61 =6
5.2 − 1 =1
6.26 − 25 =1
7.457 − 224 =233
8.936 − 418 =518
9.868 − 303 =565
10.599 − 373 =226
11.694 − 66 =628
12.742 − 232 =510
13.904 − 218 =686
14.718 − 263 =455
15.112 − 74 =38
16.513 − 419 =94
17.510 − 486 =24
18.355 − 185 =170
19.350 − 205 =145
20.960 − 831 =129
Follow the progression
Start with smaller differences, then move to hundreds, tens and ones without crossing a hundred. The next group crosses a hundred; two mixed problems finish the worksheet. Every answer is non-negative, and the optional answer sheet follows the same question numbers.
Use the nearest hundred
For 675 − 243, subtract 200, then 40, then 3: 475, 435, 432. For 504 − 126, subtract 4 to reach 500, then the remaining 122 to get 378. Add 126 back to 378 to verify the result.
