Solve 10*9*8*7/24-4*6*5/2-6-3

$$\frac{ 10 \times 9 \times 8 \times 7 }{ 24 } -4 \times \frac{ 6 \times 5 }{ 2 } -6-3$$

Evaluate

$$141$$

Solution Steps

Multiply 10 and 9 to get 90.

$$\frac{90\times 8\times 7}{24}-4\times \frac{6\times 5}{2}-6-3$$

Multiply 90 and 8 to get 720.

$$\frac{720\times 7}{24}-4\times \frac{6\times 5}{2}-6-3$$

Multiply 720 and 7 to get 5040.

$$\frac{5040}{24}-4\times \frac{6\times 5}{2}-6-3$$

Divide 5040 by 24 to get 210.

$$210-4\times \frac{6\times 5}{2}-6-3$$

Multiply 6 and 5 to get 30.

$$210-4\times \frac{30}{2}-6-3$$

Divide 30 by 2 to get 15.

$$210-4\times 15-6-3$$

Multiply 4 and 15 to get 60.

$$210-60-6-3$$

Subtract 60 from 210 to get 150.

$$150-6-3$$

Subtract 6 from 150 to get 144.

$$144-3$$

Subtract 3 from 144 to get 141.

$$141$$

Factor

$$3\times 47$$
