Math Crossword #1 Solution
Explanation:
Before solving, remember to work from left to right and top to bottom. Solve:
In Crossword Row C, we multiply and add the missing 1-9 numbers to get 22. We test all multiplication combinations, skipping repeating products. 7 x 3 + 1 does not fulfil our equations. 7×2+8=22.
In column F, we find integers that could give us a 13. 9 – 4 + 8 = 13
3 + 1 / 2 = 2 is in Column E. Next, we go to Row A, where we already have a 3 and 9, so we have one candidate. 6 x 3 / 9 = 2
Excellent! The math crossword is 90% complete. Only one digit remains to meet the equation in column D. 6 – 5 x 7 Equals 7.
Equations horizontal:
Row A=6×3/9=2
Row B => 5 + 1 – 4 = 2
7×2+8=22
Vertices
6 – 5 x 7 = 7
3+1/2 Equals 2 in column E
9-4-8 Equals 13 in column F
