It equals five.
take away the ones it is 2+2.
Next it could be a decimal like 2.5+2.5=5!
That is probably why people say "2+2=5."
End of story!

(10+9)+(1−1)+(2−2)+(3−1)+(4−4) = 21This is the same equation rewritten: (10+9)+(3−1) = 21This can be done as 1-1, 2-2, 4-4 cancel themselves out.
1/3 + 2/7 = 7/21 + 6/21 = 13/21
21, sigh.
2/3 + 1/7 + 4/6 = 14/21 + 3/21 + 14/21 = 31/21 = 1 10/21
2+1= 21 joking, it is 3
1 + 2 + 3 + 4 + 6 + 7 + 12 + 14 + 21 + 28 + 42 = 140
The result obtain from the equation 4 plus -1 -21 is -18.
It's Fibonacci's

1/2 + 1/3 * 1/7 = 1/2 + 1/21 = 21/42 + 2/42 = 23/42
As posed, the question has no answer in base 10 arithmetic.The largest digit is 9 and 9 + 1 + 2 + 3 + 1 = 16, which is way short of 21.There is no solution for other integer bases either.
1) x=21 2) x=14.45
It is: 13/21
(21)3 -(19)3 (21)2+(19)2+(399)
2/7 + 1/3= 13/21 2/7 + 1/3 =(2/7 * 3/3) + (1/3 * 7/7) = 6/21 + 7/21 = 13/21
