1+4 means multiplying 1 times 4, getting 4, then adding 1, getting 5.
2+5 means multiplying 2 times 5, getting 10, then adding 2, getting 12.
3+6 means multiplying 3 times 6, getting 18, then adding 3, getting 21.
4+7 means multiplying 4 times 7, getting 28, then adding 4, getting 32.
5+8 means multiplying 5 times 8, getting 40, then adding 5, getting 45.

My view on such problems is THIS: 

     Without appropriate explanations, it is the treatment "below the belt . . . ".


     And would my will for it, I'd momentarily redirect such posts to the TRASH section without any explanations.

For the sake of purity of this forum . . .
