3 ⋅ 5 − 7 + 18 : 3 = 14
-3-5+7+18-3 = 14. -11+25 = 14.
To solve the equation 3 _ 5 _ 7 _ 18 _ 3 = 14, we can use the operations: 3 * 5 - 7 + 18 ÷ 3. This leads us step-by-step to 14: (3 * 5 = 15), (15 - 7 = 8), and (8 + 6 = 14). Therefore, the correct signs to fill in the blanks are multiplication, subtraction, addition, and division.
