Evaluate

$$1694$$

Solution Steps

Multiply 70 and 2 to get 140. Multiply 71 and 3 to get 213. Multiply 80 and 3 to get 240. Multiply 90 and 5 to get 450. Multiply 85 and 3 to get 255. Multiply 95 and 2 to get 190. Multiply 103 and 2 to get 206.

$$140+213+240+450+255+190+206$$

Add 140 and 213 to get 353.

$$353+240+450+255+190+206$$

Add 353 and 240 to get 593.

$$593+450+255+190+206$$

Add 593 and 450 to get 1043.

$$1043+255+190+206$$

Add 1043 and 255 to get 1298.

$$1298+190+206$$

Add 1298 and 190 to get 1488.

$$1488+206$$

Add 1488 and 206 to get 1694.

$$1694$$

Factor
