79 + 103 = 182
Since 214 is a bit over 200, and 182 is a bit below 200, you could reasonably estimate them both as being 200 and therefore the sum of the two would be approximately 400. The actual sum is 396, which is very close to 400.
124 + 157 + 214 = 495
898 + 214 = 1,112
The sum of 214 and 475.2 is 689.2
78 + 182 = 260
-182 + 321 = 139
214+475.2
214 divided by 5 equal in partial quotients = 42.8
2-216 equal to = -214
2 x 107 = 214
