Solution Steps

Add 3 and 6 to get 9.

$$9-4-5+2+6-8+7=7\times 3+6-4-5+2+6-7+1\text{ and }7\times 3+6-4-5+2+6-7+1=2$$

Subtract 4 from 9 to get 5.

$$5-5+2+6-8+7=7\times 3+6-4-5+2+6-7+1\text{ and }7\times 3+6-4-5+2+6-7+1=2$$

Subtract 5 from 5 to get 0.

$$2+6-8+7=7\times 3+6-4-5+2+6-7+1\text{ and }7\times 3+6-4-5+2+6-7+1=2$$

Add 2 and 6 to get 8.

$$8-8+7=7\times 3+6-4-5+2+6-7+1\text{ and }7\times 3+6-4-5+2+6-7+1=2$$

Subtract 8 from 8 to get 0.

$$7=7\times 3+6-4-5+2+6-7+1\text{ and }7\times 3+6-4-5+2+6-7+1=2$$

Multiply 7 and 3 to get 21.

$$7=21+6-4-5+2+6-7+1\text{ and }7\times 3+6-4-5+2+6-7+1=2$$

Add 21 and 6 to get 27.

$$7=27-4-5+2+6-7+1\text{ and }7\times 3+6-4-5+2+6-7+1=2$$

Subtract 4 from 27 to get 23.

$$7=23-5+2+6-7+1\text{ and }7\times 3+6-4-5+2+6-7+1=2$$

Subtract 5 from 23 to get 18.

$$7=18+2+6-7+1\text{ and }7\times 3+6-4-5+2+6-7+1=2$$

Add 18 and 2 to get 20.

$$7=20+6-7+1\text{ and }7\times 3+6-4-5+2+6-7+1=2$$

Add 20 and 6 to get 26.

$$7=26-7+1\text{ and }7\times 3+6-4-5+2+6-7+1=2$$

Subtract 7 from 26 to get 19.

$$7=19+1\text{ and }7\times 3+6-4-5+2+6-7+1=2$$

Add 19 and 1 to get 20.

$$7=20\text{ and }7\times 3+6-4-5+2+6-7+1=2$$

Compare 7 and 20.

$$\text{false}\text{ and }7\times 3+6-4-5+2+6-7+1=2$$

Multiply 7 and 3 to get 21.

$$\text{false}\text{ and }21+6-4-5+2+6-7+1=2$$

Add 21 and 6 to get 27.

$$\text{false}\text{ and }27-4-5+2+6-7+1=2$$

Subtract 4 from 27 to get 23.

$$\text{false}\text{ and }23-5+2+6-7+1=2$$

Subtract 5 from 23 to get 18.

$$\text{false}\text{ and }18+2+6-7+1=2$$

Add 18 and 2 to get 20.

$$\text{false}\text{ and }20+6-7+1=2$$

Add 20 and 6 to get 26.

$$\text{false}\text{ and }26-7+1=2$$

Subtract 7 from 26 to get 19.

$$\text{false}\text{ and }19+1=2$$

Add 19 and 1 to get 20.

$$\text{false}\text{ and }20=2$$

Compare 20 and 2.

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

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

$$\text{false}$$
