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.

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.

Therefore, add one zero to 93.

93 x 10 = 930.
