It is: 1.15 plus 2.85 = 4
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.
400 + 900 + 1000 = 2300
300000 plus 100000 plus 400 plus 290 is equal to 400,690.
When the sum of a number plus 3 is squared, it is 11 more than the sum of the number plus 2 when squared.
Their sum is 400.

It is: 1.15 plus 2.85 = 4
500 + 400 = 900
400
2,4,8,10 and 16 are factors of 400.
The sum answer = 3440
(((800 plus 400) plus 400) plus 500) plus 500 = 2600
The sum is 1511.
