Choose a method then find the product of 70x55

First, you could just simply multiply them. 70 * 55 = 3850.

Second, remove the 0 from the 70 then you get 7. Multiply that with 55.

7 * 55 = 385. You could've done that in your head! Now we add back the zero to complete the answer: 3850.

Answer is 3850 but for the method what I did was find a calculator and I used it instead of working it out
