Not-All Inequality MinuPlu

Not-All Inequality MinuPlu is one of the rare nine MinuPlu Specials. It adds inequalites (< >) but doesn't have them between all pairs of horizontally and vertically adjacent cells like Inequality Sudoku does. The rules are long: Place a digit from 1-6 into each cell. The digits in each block must combine to produce the total shown in the top-left corner of that block, using only the mathematical operator specified (+ - x ÷). Digits may repeat in a block, but not in the same row or column. Each sign tells you if a digit is larger (>) or smaller (<) than the digit next to it. Enjoy the 6x6 sample puzzle!
