Learning time
Kids learn by watching short, engaging video lessons.
When you are solving multiplication problems where you are multiplying by 10, you can just add a zero to the end of whatever the other number in the equation is to get your answer. So, for example, if you have 2 x 10, the other number in the equation is 2. So, if you add a zero to the end of that number, you would have 2 and 0 which is 20 which means 2 x 10 = 20. If you look at the equation 5 x 10, the other number is 5. If you add a zero to the end of 5, you have 5 and 0 which is 50. That means that 5 x 10 = 50. You can do this to any equation where you're multiplying by 10. You just add zero to the end of the other number that you're multiplying by.
