Step by step help for 17.5x2.48

Start by writing it out like this:
  17.50
*  2.48  
Make sure that all the places are in correct order. Notice that I added a ZERO in the place that had nothing there.
Move the decimal point so everything is a whole number. You have moved it 4 times.
Now, starting from 8, multiply it by 0, then 5, then 7, and lastly, 1. Now go to the next number (4) and do the same, this time though, put a zero in the first spot. Every new number, add another zero. 
After you are done, add them up. Now move the decimal point starting from the right and into the number 4 times. Take out the zeros.
Your answer should be: 43.4
