Answer
67 - 21 = 46. 67 - 46 = 21.
(b)
If 198 - 98 = 100, then, 100 + ____ = 198. 198 - ____ = 98.

100 + 98 = 198. 198 - 100 = 98.
(c)
If 189 + 98 = 287, then, 287 - 98 = ____. 287 - 189 = ____.
Answer
287 - 98 = 189. 287 - 189 = 98.
(d)
If 872 - 672 = 200, then, 200 + ____ = 872. 872 - ____ = 672.
Answer
200 + 672 = 872. 872 - 200 = 672.
Explanation
(a) Using the inverse relationship: if 46 + 21 = 67, then 67 - 21 = 46 and 67 - 46 = 21. (b) If 198 - 98 = 100, then 100 + 98 = 198 and 198 - 100 = 98. (c) If 189 + 98 = 287, then 287 - 98 = 189 and 287 - 189 = 98. (d) If 872 - 672 = 200, then 200 + 672 = 872 and 872 - 200 = 672.
