Solve (0.4)(0.4+1)(0.4-1)(0.4-2)(0.001)/24

$$\frac { ( 0.4 ) ( 0.4 + 1 ) ( 0.4 - 1 ) ( 0.4 - 2 ) ( 0.001 ) } { 24 }$$

Evaluate

$$0.0000224$$

Solution Steps

Add 0.4 and 1 to get 1.4.

$$\frac{0.4\times 1.4\left(0.4-1\right)\left(0.4-2\right)\times 0.001}{24}$$

Multiply 0.4 and 1.4 to get 0.56.

$$\frac{0.56\left(0.4-1\right)\left(0.4-2\right)\times 0.001}{24}$$

Subtract 1 from 0.4 to get -0.6.

$$\frac{0.56\left(-0.6\right)\left(0.4-2\right)\times 0.001}{24}$$

Multiply 0.56 and -0.6 to get -0.336.

$$\frac{-0.336\left(0.4-2\right)\times 0.001}{24}$$

Subtract 2 from 0.4 to get -1.6.

$$\frac{-0.336\left(-1.6\right)\times 0.001}{24}$$

Multiply -0.336 and -1.6 to get 0.5376.

$$\frac{0.5376\times 0.001}{24}$$

Multiply 0.5376 and 0.001 to get 0.0005376.

$$\frac{0.0005376}{24}$$

Expand \frac{0.0005376}{24} by multiplying both numerator and the denominator by 10000000.
