Iggy is absolutely wrong. The product of 80 and 700 simply means one should multiply the two numbers. A simple technique to know the number of zero's when you multiply two numbers is adding the numbers of zero of the two multiplicand.
The multiplicands 80 and 700 has 1 and 2 zero's respectively . The total number of zero's is 3. Then, the product of 7 and 8 has no zero so definitely we only have the 3 zero's . The product of 8 and 7 is 56 . Therefore , we add only the 3 zero's to get 56, 000.
