Metal AX BX CX DX EX

A - + + + +

B + - + - -

C + + - + -

D - - - - -

E + + + + -

Arrange the following metals A,B,C,D and E according to increasing reactivity out of the information

given above. Use The Symbol of greater than (>) in indicating that one metal is more reactive than the other. Ex A>B>E means metal A is more reactive than B and B is more reactive than E.

I dont know where to start ther'r so many elements

I know that B + AX = there is a reaction in which B > A

but i tried solving other elements and some gave me an A < B
