Solution Steps

Multiply 5 and 20 to get 100. Multiply 4 and 21 to get 84. Multiply 22 and 3 to get 66. Multiply 23 and 3 to get 69. Multiply 24 and 3 to get 72. Multiply 25 and 2 to get 50. Multiply 26 and 2 to get 52.

$$\frac{100+84+66+69+72+50+52}{1}$$

Add 100 and 84 to get 184.

$$\frac{184+66+69+72+50+52}{1}$$

Add 184 and 66 to get 250.

$$\frac{250+69+72+50+52}{1}$$

Add 250 and 69 to get 319.

$$\frac{319+72+50+52}{1}$$

Add 319 and 72 to get 391.

$$\frac{391+50+52}{1}$$

Add 391 and 50 to get 441.

$$\frac{441+52}{1}$$
