Answer: 56 = 50 + 6
Explanation:
You can break apart a factor of a multiplication problem to help compute the product.
After braking apart the multiple digit factor into their ones, tens, hundreds, ... you can multiply the other factor by each part of the broken factor and then add the separate products to find the total product.
Let's do an expample with the given number, 56.
Being 56 a two-digit number you can break it up by tens and ones. In this way, 56 becomes 5 tens and 6 ones, i.e. 50 + 6.
Then you can multiply the other factor times 50 + 6 and get the product.
Let's say the other factor is 7, i.e. you want to find the product 7 × 56.
Therefore, 56 = 50 + 6 and 7 × 56 = 7 × 50 + 7 × 6
7 × 50 = 350
7 × 6 = 42
-------------------------
350 + 42 = 392
As you see, after braking apart the two digit factor 56 as per the place values of the digits, 50 and 6, you can find the product by adding the two separate products: 350 + 42 = 392.
