Solution Steps

Subtract 2 from -4 to get -6.

$$-6+3-\left(-5+7-9+1\right)=3\text{ and }40-\left(65-84\right)=60$$

Add -6 and 3 to get -3.

$$-3-\left(-5+7-9+1\right)=3\text{ and }40-\left(65-84\right)=60$$

Add -5 and 7 to get 2.

$$-3-\left(2-9+1\right)=3\text{ and }40-\left(65-84\right)=60$$

Subtract 9 from 2 to get -7.

$$-3-\left(-7+1\right)=3\text{ and }40-\left(65-84\right)=60$$

Add -7 and 1 to get -6.

$$-3-\left(-6\right)=3\text{ and }40-\left(65-84\right)=60$$

The opposite of -6 is 6.

$$-3+6=3\text{ and }40-\left(65-84\right)=60$$

Add -3 and 6 to get 3.

$$3=3\text{ and }40-\left(65-84\right)=60$$

Compare 3 and 3.

$$\text{true}\text{ and }40-\left(65-84\right)=60$$

Subtract 84 from 65 to get -19.

$$\text{true}\text{ and }40-\left(-19\right)=60$$

The opposite of -19 is 19.

$$\text{true}\text{ and }40+19=60$$

Add 40 and 19 to get 59.

$$\text{true}\text{ and }59=60$$

Compare 59 and 60.

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

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

$$\text{false}$$
