If 0=3, 1=2, 2=3 and 3=6 then 4=?

Question

If,

5 + 3 = 835

2 + 4 = 642

7 + 0 = 707

Then,

6 + 1 = ???

Answer 1

you begin multiplying by (-1) and adding (+3). as you proceed you should end up multiplying by (+3) and adding (-1).
0x(-1)+3=3
1x(0)+2=2
2x(1)+1=3
3x(2)+0=6
4x(3)+(-1)=11

the golnum

Answer 2

0×2=0+(3)=3
1×2=2+(0)=2
2×2=4+(-1)=3
3×2=6+(0)=6

4×2=8+(3)=11
Ist multiply 2 then add this Sequence i.e 3 ,0, (-1),0 ,3.
