Solve 1-(3-1+6-3)+6(200+45+30)-400

$$1 - ( 3 - 1 + 6 - 3 ) + 6 ( 200 + 45 + 30 ) - 400$$

Evaluate

$$1246$$

Solution Steps

Subtract 1 from 3 to get 2.

$$1-\left(2+6-3\right)+6\left(200+45+30\right)-400$$

Add 2 and 6 to get 8.

$$1-\left(8-3\right)+6\left(200+45+30\right)-400$$

Subtract 3 from 8 to get 5.

$$1-5+6\left(200+45+30\right)-400$$

Subtract 5 from 1 to get -4.

$$-4+6\left(200+45+30\right)-400$$

Add 200 and 45 to get 245.

$$-4+6\left(245+30\right)-400$$

Add 245 and 30 to get 275.

$$-4+6\times 275-400$$

Multiply 6 and 275 to get 1650.

$$-4+1650-400$$

Add -4 and 1650 to get 1646.

$$1646-400$$

Subtract 400 from 1646 to get 1246.

$$1246$$

Factor

$$2\times 7\times 89$$
