Answer:
-140,000
Explanation:
Here's a trick I learned in 5th grade.
You see all the zero's behind the number 10,000 just add them onto the back of the number you're mutliplying with and it gives you the answer.
In this case, we have the number 10,000 with 4 zero's and we're going to add that to the back of 14 which gives us the answer 140,000 And they both have 4 zero's. :)
Therefore, the answer is 140,000
Hope this Helps!
Have a great day!
