# Rowmix

One puzzle type occasionally appearing in Visie, a magazine of the Evangelical Broadcast in the Netherlands, is something the author calls “All mixed up”. I prefer “Rowmix” for reasons which will be clear once you have take a look at the puzzle rules.

Rowmix nr 1*

 5 6 7 8 1 /2 +7 -5 x5 15 2 x4 -1 +3 /2 12 3 +8 +3 /2 -1 8 4 +7 +7 -6 -2 10 12 8 15 22

Shuffle the numbers in every row so that a correct calculation is formed in every row and column. In doing so, all calculations are performed strictly from left to right or from top to bottom. There is no precedence of multiplication and division over addition and subtraction, and neither are there any brackets to be inserted.

For example: In the first row above you should, starting with 1, using /2, +7, -5, and x5, make 15.

Rowmix nr 2*

 12 12 12 12 10 /2 -3 +4 +1 5 10 x2 /2 +5 -10 10 10 +10 -9 -5 -1 5 10 +14 +6 +3 +2 35 24 12 12 12

Rowmix nr 3*

 1 2 3 4 1 x3 /2 +8 +7 20 2 /4 +6 +2 +2 3 3 +6 +4 +3 -10 6 4 /2 +4 +3 +3 10 20 3 8 10
