2x 3x, 4x, 5x, 7x etc, over two squares have only one set of options: 1 and the number.
So you see examples of 6x, 8x in other puzzles but not these. I don't know why this is, but it is this way in other puzzle books.
Also you see 2/, 3/, 4/ in puzzles, but never 5/, 7/ where there would only be one combination of options.
I'll admit it is odd because you see 3+ (or 17+ in a 9x9) and that has only one option.
