 Here's an easy way to multiply 5 by any even number. The trick is to divide that other number by 2 and then add a 0. Let's take 5 times 8. So if we divide 8 by 2, we'll have 4. Add a 0 to that, and that gives us 40. So 5 times 8 equals 40. Let's try one more. Say your mom asks you to pick up 5 dozen donuts. That's 5 boxes with 12 donuts each. If we take that 12 and divide it by 2, we'll get 6. And if we add a 0 to that, that's 60. So 5 times 12 equals 60 donuts. That's a lot of donuts. Subscribe to WISC online to learn better.
