The answer is 24. Simply add the numbers together like you would for two plus two. To check your work, a calculator is the best option.
2 + 3 + 4 + 5 + 6 = 20
-5-1 plus 4 plus 2-6 plus 4 is equal to -2
2 + 1 + 5 + 52 + 4 + 6 = 70
4-5 plus 5-6 = -2
1 + 2 + 3 + 4 + 5 + 6 + 100 = 121
2 + 2 = 4 +2 = 6 + 5 = 11
30. 2+3+5=10, 4+6=10, and 2+4+1+1+2=10.
4 + 6 + 6 + 5 + 5 + 4 + 6 + 5 + 5 + 6 + 5 + 5 + 5 + 3 = 70
It is 4 and 5/6.
9 + 6 + 9 + 6 + 9 + 8 + 5 + 2 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 99
4-5+6+2-10= -3
