Solve 32*80-0.2*80^2+12*120-0.05*120^2

$$32 \times 80 - 0.2 \times 80 ^ { 2 } + 12 \times 120 - 0.05 \times 120 ^ { 2 }$$

Evaluate

$$2000$$

Solution Steps

Multiply 32 and 80 to get 2560.

$$2560-0.2\times 80^{2}+12\times 120-0.05\times 120^{2}$$

Calculate 80 to the power of 2 and get 6400.

$$2560-0.2\times 6400+12\times 120-0.05\times 120^{2}$$

Multiply 0.2 and 6400 to get 1280.

$$2560-1280+12\times 120-0.05\times 120^{2}$$

Subtract 1280 from 2560 to get 1280.

$$1280+12\times 120-0.05\times 120^{2}$$

Multiply 12 and 120 to get 1440.

$$1280+1440-0.05\times 120^{2}$$

Add 1280 and 1440 to get 2720.

$$2720-0.05\times 120^{2}$$

Calculate 120 to the power of 2 and get 14400.

$$2720-0.05\times 14400$$

Multiply 0.05 and 14400 to get 720.

$$2720-720$$

Subtract 720 from 2720 to get 2000.

$$2000$$

Factor

$$2^{4}\times 5^{3}$$
