Solve 64*(-5,9-4)+7-7*(67-76)

$$64 \cdot ( - 5,9 - 4 ) + 7 - 7 \cdot ( 67 - 76 )$$

Evaluate

$$-563,6$$

Solution Steps

Subtract 4 from -5,9 to get -9,9.

$$64\left(-9,9\right)+7-7\left(67-76\right)$$

Multiply 64 and -9,9 to get -633,6.

$$-633,6+7-7\left(67-76\right)$$

Add -633,6 and 7 to get -626,6.

$$-626,6-7\left(67-76\right)$$

Subtract 76 from 67 to get -9.

$$-626,6-7\left(-9\right)$$

Multiply 7 and -9 to get -63.

$$-626,6-\left(-63\right)$$

The opposite of -63 is 63.

$$-626,6+63$$

Add -626,6 and 63 to get -563,6.

$$-563,6$$

Factor
