Your friend iggy tells you that the product of 80 and 700 will have four zeroes. explain to iggy why his estimation is incorrect, and how to fix it.

80 × 700 = 56000

Step-by-step explanation:

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.

80 × 700 = 56000

The estimation is definitely incorrect.
