$$\text{false}\text{ and }234-21\times 16=336$$

Multiply 21 and 16 to get 336.

$$\text{false}\text{ and }234-336=336$$

Subtract 336 from 234 to get -102.

$$\text{false}\text{ and }-102=336$$

Compare -102 and 336.

$$\text{false}\text{ and }\text{false}$$

The conjunction of \text{false} and \text{false} is \text{false}.

$$\text{false}$$
