Lincoln PD has 11 cars. They averaged 83 patrol miles during the day. How many miles did they drive in total?

  1. 913 miles
  2. 917 miles
  3. 922 miles
  4. 931 miles
  5. 934 miles
Explanation

Answer: A - 913 miles.

To multiply a number by 11:

Rewrite the first number with a space between:

8_3

Then, add those two numbers together (to get 11), and put that in the space. Since the sum of the two digits is greater than 9, you must carry the 1.

913 miles is the answer.

Key Takeaway: Practice with 10 different numbers and you will blaze through multiplying by 11 when it counts.
