Answer:
1982 ÷ 18 = 109
Step-by-step explanation:
The operator can't be addition, subtraction, or multiplication, because wherever you place it, the result is not 109.
The operator must be division. It must be in the fourth or fifth place, to make the numerator greater than the denominator.
In the fourth place,
1982 ÷ 18 = 109
