Solve (20*30div2+20+(20*30+7*40+13*20div2)*13)div13

$$(20 \times 30 \div 2+20+(20 \times 30+7 \times 40+13 \times 20 \div 2) \times 13) \div 13$$

Evaluate

$$\frac{13450}{13}\approx 1034.615384615$$

Solution Steps

Multiply 20 and 30 to get 600.

$$\frac{\frac{600}{2}+20+\left(20\times 30+7\times 40+\frac{13\times 20}{2}\right)\times 13}{13}$$

Divide 600 by 2 to get 300.

$$\frac{300+20+\left(20\times 30+7\times 40+\frac{13\times 20}{2}\right)\times 13}{13}$$

Add 300 and 20 to get 320.

$$\frac{320+\left(20\times 30+7\times 40+\frac{13\times 20}{2}\right)\times 13}{13}$$

Multiply 20 and 30 to get 600. Multiply 7 and 40 to get 280.

$$\frac{320+\left(600+280+\frac{13\times 20}{2}\right)\times 13}{13}$$

Add 600 and 280 to get 880.

$$\frac{320+\left(880+\frac{13\times 20}{2}\right)\times 13}{13}$$

Multiply 13 and 20 to get 260.

$$\frac{320+\left(880+\frac{260}{2}\right)\times 13}{13}$$

Divide 260 by 2 to get 130.

$$\frac{320+\left(880+130\right)\times 13}{13}$$

Add 880 and 130 to get 1010.

$$\frac{320+1010\times 13}{13}$$

Multiply 1010 and 13 to get 13130.

$$\frac{320+13130}{13}$$

Add 320 and 13130 to get 13450.

$$\frac{13450}{13}$$

Factor

$$\frac{2 \cdot 5 ^ {2} \cdot 269}{13} = 1034\frac{8}{13} = 1034.6153846153845$$
