The sum of 16+2=18, and half of that is 9, so the question would be 16 minus what equals 9. So, the answer would be 7.
The difference is 6.
7272 * * * * * WRONG! Sum from 23 to 123 = (sum from 1 to 123) minus (sum from 1 to 22) = 123*124/2 - 22*23/2 = 7626 - 253 = 7373. NOT 7272!
The product is 1254. The sum is 79.
30 plus 30 equals 60 and 60 minus 38 equals 22
38 minus 16 is 22.
43 minus the sum of 16 and 11 can be calculated as follows: 16 + 11 = 27 43 - 27 = 16 Therefore, 43 minus the sum of 16 and 11 is equal to 16.
-16 - 6 = -22
