Solve 17*2+18*45*9*27-42*66/1.8

$$17 \cdot 2+18 \cdot 45 \times 9 \cdot 27- \frac{ 42 \cdot 66 }{ 1.8 }$$

Evaluate

$$195324$$

Solution Steps

Multiply 17 and 2 to get 34. Multiply 18 and 45 to get 810.

$$34+810\times 9\times 27-\frac{42\times 66}{1.8}$$

Multiply 810 and 9 to get 7290.

$$34+7290\times 27-\frac{42\times 66}{1.8}$$

Multiply 7290 and 27 to get 196830.

$$34+196830-\frac{42\times 66}{1.8}$$

Add 34 and 196830 to get 196864.

$$196864-\frac{42\times 66}{1.8}$$

Multiply 42 and 66 to get 2772.

$$196864-\frac{2772}{1.8}$$

Expand \frac{2772}{1.8} by multiplying both numerator and the denominator by 10.

$$196864-\frac{27720}{18}$$

Divide 27720 by 18 to get 1540.

$$196864-1540$$

Subtract 1540 from 196864 to get 195324.

$$195324$$

Factor
