About This Quiz
Calling all math-lovers out there: If you love to multiply numbers for fun, you'll have a blast trying to multiply the numbers in this quiz together! Some questions are pretty easy, like 7 times 11 (which is 77) while others require you to know how to multiply square roots, squared and cubed numbers, and decimals together.
Let's warm up with a few practice problems. Try and guess what 10 times 5 is. The answer should come to you pretty quickly: 50! Now how about 10 times -2? Since we're multiplying one negative number and one positive number together, the answer will always be negative. So in this case, -20 is the right answer.
Now let's try to multiply square roots together. Before multiplying square roots, it's important to take the actual square root of a number first. For example, let's try and figure out what √25 times √1 is. Well, the square root of 25 is 5, since 5 times 5 is 25. The square root of 1 is 1 because 1 times 1 is 1. So, the problem becomes 25 times 1, which is 25!
Now that you've seen some warm-ups, we think you're ready to ace this mental multiplication quiz! Good luck!
Do you think you know what 7 times 7 is?
49
When you multiply 7 times 7, you get 49. This means that the square root of 49 is also 7.
6 is the correct answer. When you multiply 24 by .25, you're just separating that number into fourths, or quarters. In other words, 6(4) is 24, which is the same thing as 24 times .25.
-5 is correct. Multiplying a number by .25 is just quartering that number, so when you quarter 20, you get 5. But since .25 is negative, it becomes -5.
The answer is .60. While the problem looks tricky, just break it down step by step. √36 is 6, since 6 times 6 is 36. 10% can be rewritten as .10, so now the problem is .10 times 6, which is .6. You're just moving the invisible decimal place in front of the 6 to the left once.
