Question

The sum of partial products is equal to the final product?

Answer 1

yep! That's right, ex. 13+4=17, also, 10+3+4=17

Answer 2

Yes, the sum of partial products is equal to the final product.

Explanation:

We need to check whether the sum of partial products is equal to the final product.

Let as consider the expression
`12* 25`.

The product of this expression is

`12* 25=300`

Write each numbers as the sum of place values.

`12=10+2`

`25=20+5`

Now, find the partial products.

| 10 2

----------|--------------------------------------------

20 | 20×10=200 20×2=40

5 | 5×10=50 5×2=10

----------|---------------------------------------------

Sum of partial products is

`200+40+50+10=300`

Therefore, the sum of partial products is equal to the final product.
