-1*-1
(-2+1)(-2+1)
-2*-2+1*-2+1*-2+1*1
since multiplication is repeated addition
then
-1*-1*4+(-2)+(-2)+(1)
let -1*-1=x
-1*-1=-1*-1*4-2-2+1
x=x*4-4+1
x=4x-3
3=4x-x
3=3x
3/3=x
1=x
thus -1*-1=x=1
No it equals 2 10 plus 1 equals 11
nothing but 11 multiplyed by 1 equals 11. 11x1=11
12
1
1 x 11, 11 x 1.
One-eleventh (1/11)
7/11 equals 21/33 1/3 equals 11/33 21/33 - 11/33 equals 10/33.
In 3n-1 equals 11, n is 4.3n - 1 = 113n - 1 + 1 = 11 + 13n = 123n/3 = 12/3n = 4
The answer is 4. 3x4 - 1 =11 12 - 1 = 11

Only one and eleven. Eleven is a prime number. Prime numbers are divisible by one and themselves only.
XI= 11 because X equals 10 and I equals 1. So take X+I (10+1) and get XI (11)
