To solve the crossword puzzle, we need to fill in the blanks with numbers that satisfy the given mathematical operations and ensure all equations are true. Let's go through the puzzle step by step.
Step 1: Analyze the structure
The crossword consists of horizontal and vertical equations. Each equation must be solved correctly, and the numbers must fit into the grid seamlessly.
Step 2: Solve each equation
We will solve the equations one by one, starting from the top-left corner and moving systematically.
#### Top Row:
1.
36 ÷ 6 = 6 (Already filled)
2.
4 × 7 = 28 (Already filled)
3.
32 + 19 = 51 (Already filled)
#### Second Row:
1.
44 - ? = 80 - 38
- 80 - 38 = 42
- So, 44 - ? = 42 → ? = 2
2.
? ÷ 7 = 8
- ? = 8 × 7 = 56
3.
23 + ? = 44
- 44 - 23 = 21 → ? = 21
4.
16 ÷ 8 = 2 (Already filled)
5.
? - ? = 27
- We need two numbers that subtract to 27. Let's use 54 and 27.
- So, 54 - 27 = 27
#### Third Row:
1.
15 + ? = 30
- 30 - 15 = 15 → ? = 15
2.
18 ÷ 9 = 2 (Already filled)
3.
35 - ? = 89 - 36
- 89 - 36 = 53
- So, 35 - ? = 53 → ? = -18 (This seems incorrect; let's recheck the grid for consistency.)
4.
36 + 12 = 48 (Already filled)
#### Fourth Row:
1.
30 ÷ 5 = 6 (Already filled)
2.
7 × 9 = 63 (Already filled)
3.
4 + 4 = 8 (Already filled)
#### Fifth Row:
1.
45 + 9 = 54 (Already filled)
2.
14 + ? = 27
- 27 - 14 = 13 → ? = 13
3.
35 - 26 = 9 (Already filled)
4.
5 + 6 = 11
#### Sixth Row:
1.
55 + 45 = 100 (Already filled)
2.
45 ÷ 5 = 9 (Already filled)
3.
9 × 9 = 81 (Already filled)
#### Seventh Row:
1.
34 + ? = 89
- 89 - 34 = 55 → ? = 55
2.
70 ÷ 10 = 7 (Already filled)
3.
52 - 25 = 27 (Already filled)
4.
3 × 7 = 21 (Already filled)
#### Eighth Row:
1.
23 - 16 = 7 (Already filled)
2.
72 + 5 = 77 (Already filled)
3.
3 × 8 = 24 (Already filled)
#### Ninth Row:
1.
58 + ? = 81
- 81 - 58 = 23 → ? = 23
2.
63 ÷ 7 = 9 (Already filled)
3.
61 - 5 = 56 (Already filled)
#### Tenth Row:
1.
81 - 32 = 49 (Already filled)
2.
8 × 2 = 16 (Already filled)
3.
15 - 11 = 4 (Already filled)
