Solve 5left(-1-1right)-3left(-2+9right)-7left(-3-1right)

$$5 \left( -1-1 \right) -3 \left( -2+9 \right) -7 \left( -3-1 \right)$$

Evaluate

$$-3$$

Solution Steps

Subtract 1 from -1 to get -2.

$$5\left(-2\right)-3\left(-2+9\right)-7\left(-3-1\right)$$

Multiply 5 and -2 to get -10.

$$-10-3\left(-2+9\right)-7\left(-3-1\right)$$

Add -2 and 9 to get 7.

$$-10-3\times 7-7\left(-3-1\right)$$

Multiply 3 and 7 to get 21.

$$-10-21-7\left(-3-1\right)$$

Subtract 21 from -10 to get -31.

$$-31-7\left(-3-1\right)$$

Subtract 1 from -3 to get -4.

$$-31-7\left(-4\right)$$

Multiply 7 and -4 to get -28.

$$-31-\left(-28\right)$$

The opposite of -28 is 28.

$$-31+28$$

Add -31 and 28 to get -3.

$$-3$$

Factor

$$-3$$
