Solution Steps

Add 10000 and 20000 to get 30000.

$$30000+30000+50000=110000\text{ and }30000+20000+20000+10000=80000$$

Add 30000 and 30000 to get 60000.

$$60000+50000=110000\text{ and }30000+20000+20000+10000=80000$$

Add 60000 and 50000 to get 110000.

$$110000=110000\text{ and }30000+20000+20000+10000=80000$$

Compare 110000 and 110000.

$$\text{true}\text{ and }30000+20000+20000+10000=80000$$

Add 30000 and 20000 to get 50000.

$$\text{true}\text{ and }50000+20000+10000=80000$$

Add 50000 and 20000 to get 70000.

$$\text{true}\text{ and }70000+10000=80000$$

Add 70000 and 10000 to get 80000.

$$\text{true}\text{ and }80000=80000$$

Compare 80000 and 80000.

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

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

$$\text{true}$$
