4 + 2 + 10 + 50 = 66
1 plus 2 plus 3 plus 4 equal 10. 10 times 5 equals 50.
-10
1+2 = 3 1+2+3 = 6 1+2+3+4 = 10 1+2+...+ N = 1/2(N+1)N if N = 50, 1+2+...+50 = 1/2 x 51 x 50 = 1275 Since 2+4+6+...+100 = 2 x (1+2+3+...+50) = 2 x 1275 = 2550
30. 2+3+5=10, 4+6=10, and 2+4+1+1+2=10.
-2 + 10 - 8 + 4 - 3 + 2 = 3
correct!! 2 plus 2 does equal 4!! yay u!!
The answer is 2 because 10 plus 2 is really 12 and 6 plus 4 is 10 so 12 is 2 more than 10which means you have to take 2 from 4 which gives you the answer.
2+4+8+2+10+6 = 6+8+2+10+6 = 14+2+10+6 = 16+10+6 = 26+6 = 32
If we add -10 and -2 and -4, we get -16.
No, 1 + 2 + 3 + 4 + 5 = 15.
2 + 6n + 4, with n = 10 then 2 + 6(10) + 4 2 + 60 + 4 62 + 4 66
6x + 10 + 4x = 5010x + 10 = 5010x = 40x = 4
