Solve 1-0.25*0.35-0.4*0.35-0.4*0.25-0.4*0.25*0.35

$$1-0.25 \times 0.35-0.4 \times 0.35-0.4 \times 0.25-0.4 \times 0.25 \times 0.35$$

Evaluate

$$0.6375$$

Solution Steps

Multiply 0.25 and 0.35 to get 0.0875.

$$1-0.0875-0.4\times 0.35-0.4\times 0.25-0.4\times 0.25\times 0.35$$

Subtract 0.0875 from 1 to get 0.9125.

$$0.9125-0.4\times 0.35-0.4\times 0.25-0.4\times 0.25\times 0.35$$

Multiply 0.4 and 0.35 to get 0.14.

$$0.9125-0.14-0.4\times 0.25-0.4\times 0.25\times 0.35$$

Subtract 0.14 from 0.9125 to get 0.7725.

$$0.7725-0.4\times 0.25-0.4\times 0.25\times 0.35$$

Multiply 0.4 and 0.25 to get 0.1.

$$0.7725-0.1-0.4\times 0.25\times 0.35$$

Subtract 0.1 from 0.7725 to get 0.6725.

$$0.6725-0.4\times 0.25\times 0.35$$

Multiply 0.4 and 0.25 to get 0.1.

$$0.6725-0.1\times 0.35$$

Multiply 0.1 and 0.35 to get 0.035.

$$0.6725-0.035$$

Subtract 0.035 from 0.6725 to get 0.6375.

$$0.6375$$

Factor

$$\frac{3 \cdot 17}{5 \cdot 2 ^ {4}} = 0.6375$$
