The anser is 21.I figured it out by looking at row 4.Row 4 equals20 and 20 divided by 4 equals5 and then 20 divided by 3 equals
6 remander 2 and 6 plus 6 plus 6 equals18.20 minise 18 equals 2.so square is 2 and cical is 6.Row 3 is 18 so 6 plus 6 plus 6 equals 18 but there is another letter so circal cant equal 6. and in row 4 5 would not work so maby 4 will 4 times 3 equals12 and 20-12=8 so cical=4 and square=8 and row 3 4 times 3=12 and 18-12=6 so triangel=6.row2 if squre equals8 then 8+8=16 30-16=14 14 divided by2 equals7 so hexagon=7.colom1 7+6=13+4 times 2 =21
