Multiply Numbers by Multiples of 10, 100, 1000, etc. 1. Box out the digits (natural/counting numbers). Multiply them together. 2. Count the zeroes in both FACTORS using a . Place that many zeroes in the PRODUCT. ï The TOTAL number of zeroes in both factors should equal the number of zeroes in the product. **be careful when dealing with products that are multiples of 10- make sure you are not short a zero!** 3,000 x 70 = 210, 000 600 x 50 = 30,000 4,000 x 80 = 320,000 90 x 600,000 = 54,000,000 800 x 100 = 80,000 200 x 150 = 30,000 400 x 5,000 = 2,000,000 7,000 x 800 = 5,600,000
