Answer:
178 chairs
Step-by-step explanation:
(something) rows of (something) columns always means to multiply. So, let's multiply 8 x 23:
8 × 23 = 184
Now, since the workers removed 6 of the chairs, there are 6 less chairs in the theater. Let's subtract 6 from 184 to get our final answer:
184 - 6 = 178
