$$( \left( 8+8+8+8+4.5+8+9+9+9+9 \right) 14)+(21(3+1+1+.75)$$

Evaluate

$$1247.75$$

Solution Steps

Add 8 and 8 to get 16.

$$\left(16+8+8+4.5+8+9+9+9+9\right)\times 14+21\left(3+1+1+0.75\right)$$

Add 16 and 8 to get 24.

$$\left(24+8+4.5+8+9+9+9+9\right)\times 14+21\left(3+1+1+0.75\right)$$

Add 24 and 8 to get 32.

$$\left(32+4.5+8+9+9+9+9\right)\times 14+21\left(3+1+1+0.75\right)$$

Add 32 and 4.5 to get 36.5.

$$\left(36.5+8+9+9+9+9\right)\times 14+21\left(3+1+1+0.75\right)$$

Add 36.5 and 8 to get 44.5.

$$\left(44.5+9+9+9+9\right)\times 14+21\left(3+1+1+0.75\right)$$

Add 44.5 and 9 to get 53.5.

$$\left(53.5+9+9+9\right)\times 14+21\left(3+1+1+0.75\right)$$

Add 53.5 and 9 to get 62.5.

$$\left(62.5+9+9\right)\times 14+21\left(3+1+1+0.75\right)$$

Add 62.5 and 9 to get 71.5.

$$\left(71.5+9\right)\times 14+21\left(3+1+1+0.75\right)$$

Add 71.5 and 9 to get 80.5.

$$80.5\times 14+21\left(3+1+1+0.75\right)$$

Multiply 80.5 and 14 to get 1127.

$$1127+21\left(3+1+1+0.75\right)$$

Add 3 and 1 to get 4.

$$1127+21\left(4+1+0.75\right)$$

Add 4 and 1 to get 5.

$$1127+21\left(5+0.75\right)$$

Add 5 and 0.75 to get 5.75.

$$1127+21\times 5.75$$

Multiply 21 and 5.75 to get 120.75.

$$1127+120.75$$

Add 1127 and 120.75 to get 1247.75.

$$1247.75$$

Factor

$$\frac{7 \cdot 23 \cdot 31}{2 ^ {2}} = 1247\frac{3}{4} = 1247.75$$
