In 2010, the national debt of the united states was about 14 trillion dollars. in 2003 it was about 7 x 10 to the 12 dollars. about how many times larger was the national debt in 2010 than 2003? this is scientific notation

 About 2 times.

Step-by-step explanation:

Given : In 2010, the national debt of the United States was about 14 trillion dollars.

We know that 1 trillion

then, In 2010, the national debt of the United States was about

dollars.

In 2003 it was about dollars.

Now, the number of times the national debt was larger in 2010 than 2003 :-

Hence, national debt was about 2 times larger in 2010 than 2003 .

7-10 is -3.

Step-by-step explanation:

When you are subtracting 7 from 10 you have to stop at 0. Well you don't exactly stop. You have to keep going even though 0 is what you might think is the lowest number possible. You still have to subtract 3. Well, the next number to 0 is -1. Then -2. Then -3 which will be your answer. This is the same for all numbers. For example, 3-6 will give you -3. 6-12 will give you -6.

I hope this makes more sense. :)
