31 Because, twice 31 is 62. And, 62 plus 13 is 75.
The sum of the numbers given is 31. 1 + 2 + 4 + 8 + ... + 2n = 2n+1 - 1
500 + 680 + 031 ------- 1,211
31+32+33 = 96
30*31/2 = 465
19 plus 12 equals 31. This is because addition is a mathematical operation that combines two numbers to find their total sum. In this case, adding 19 and 12 together results in a sum of 31.

15.25 plus 15.75 is 31
That would be 34.
31 Because, twice 31 is 62. And, 62 plus 13 is 75.
The sum of the numbers given is 31. 1 + 2 + 4 + 8 + ... + 2n = 2n+1 - 1
Expressed in octal, the decimal sum 27 + 31 = 58 would be expressed: 33 + 37 = 72
16 + 31 = 31 + 16This shows COMMUTATIVE PROPERTY OF ADDITION. It means that changing the order of the addends does not affect the sum.
500 + 680 + 031 ------- 1,211
Oh, dude, math time! So, if you add up all those numbers, you get 209. It's like, basic addition, you know? Just throw those numbers together and boom, you've got the answer. Math can be fun... sometimes.
