Do you still remember how we multiply a two-digit number by a single-digit number? Let's practice with this problem:
When we multiply a tens number by a single-digit number, the product equals a tens number. What does our problem say again? Our problem says 8 tens times 3. Therefore, how many tens do we have? The number of tens we have is 24 tens, or 240.
In our problem, the tens number, 80, has one zero. Our product (answer), 240, also has one zero.
Let's look at this new problem:
What do you notice in our new problem? The top number, 400, has two zeros. In this case, our product will also end in two zeros.
What is 4 times 5? The product equals 20. So our product of 400 times 5 is 20 hundreds, or two thousand.
Let's try again with this problem:
There are two zeros in 500, so we can already put the two zeros in our product.
Then we solve for 5 times 6. What is the answer? The product of 5 times 6 equals 30. So our product is 30 hundreds, or three thousand.
