5 x 3 = 15. 15 + 2 = 17. Write down 17 to the left of the 5. The first
subproduct is 175.

Next, multiply 35 by 20. Place a zero in the ones (units) column and
then multiply by 2. 2 x 5 = 10. Write down 0 and carry the 1.

2 x 3 is 6. 6 + 1 = 7. Write down 7 next to the 0. The second
subproduct is 700.
35
x 25
175
700

Add the two subproducts. 175 + 700 = 875. This is the product.

b. When multiplying any factor by 10, 100, 1000 and so on, add to the factor the
same number of zeros that are in the second factor.
EXAMPLE: Multiply 93 by 10. There is one zero in the 10.
Therefore, add one zero to 93.
93 x 10 = 930.
