No.
2.36 + 9.8 = 12.16
23.6 + 9.8 = 33.4
303
It is 98*6 = 588

476
They can be 31+67 = 98
If you add all the numbers from 1 to 98, the total is 4851.
Because the correct sum of 305 and 98 is 403.
303
98 because 6 plus each angle would be 98
The answer to this sum is 2010198.
Since 98 is 100 minus 2, you can think of this as 136 + 100 - 2, or 236 - 2, the answer being 234.
It is 98*6 = 588
14x20
the "sum" means to add the numbers, therefore:98 + 126 = 224
34 + 98 + 98 + 87 + 32 = 349
98 + 12087 = 12185
465 + 98 = 563
