Intermediate Cross Figure Puzzles: Volume 2

This is volume 2 in a series of intermediate Cross Figure puzzles.
A Cross Figure is like a crossword, but it uses numbers instead of letters.
Each digit occupies a cell and can be part of a "word" in the across and down directions.
Each clue is a mathematical relationship with other clues. For example, a puzzle might have the clue that 1 Across equals 4 Across plus 6 Down.
