$$145=\frac{290}{2}\text{ and }\frac{290}{2}=145$$

Divide 290 by 2 to get 145.

$$145=145\text{ and }\frac{290}{2}=145$$

Compare 145 and 145.

$$\text{true}\text{ and }\frac{290}{2}=145$$

Divide 290 by 2 to get 145.

$$\text{true}\text{ and }145=145$$

Compare 145 and 145.

$$\text{true}\text{ and }\text{true}$$

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

$$\text{true}$$
