Solve 8*90+8.2*84+8.4*83+8.6*80+8.8*75+9*68

$$8 \times 90+8.2 \times 84+8.4 \times 83+8.6 \times 80+8.8 \times 75+9 \times 68$$

Evaluate

$$4066$$

Solution Steps

Multiply 8 and 90 to get 720. Multiply 9 and 68 to get 612.

$$720+8.2\times 84+8.4\times 83+8.6\times 80+8.8\times 75+612$$

Multiply 8.2 and 84 to get 688.8.

$$720+688.8+8.4\times 83+8.6\times 80+8.8\times 75+612$$

Add 720 and 688.8 to get 1408.8.

$$1408.8+8.4\times 83+8.6\times 80+8.8\times 75+612$$

Multiply 8.4 and 83 to get 697.2.

$$1408.8+697.2+8.6\times 80+8.8\times 75+612$$

Add 1408.8 and 697.2 to get 2106.

$$2106+8.6\times 80+8.8\times 75+612$$

Multiply 8.6 and 80 to get 688.

$$2106+688+8.8\times 75+612$$

Add 2106 and 688 to get 2794.

$$2794+8.8\times 75+612$$

Multiply 8.8 and 75 to get 660.

$$2794+660+612$$

Add 2794 and 660 to get 3454.

$$3454+612$$

Add 3454 and 612 to get 4066.

$$4066$$

Factor

$$2\times 19\times 107$$
