I need Math help ...thank you

for subtraction, we have to subtract the smallest counting number from the largest counting number.If your talking about a line graph like my 4th grader uses, you can easily do add/sub as you simply count up or down the line.......
If a and b are any two real numbers, explain how calculate the difference a - b . Be sure to include the following in your explanation :

a. A description of the relationship between addition and subtraction.
b. How you can use a number line to help with the calculation.
c. How you can determine the sign of the results.

I will be picking BEST ANSWER please no negative comments about how I need to start listening in class -.- Thank you :)

The relationship between addition and subtraction is inverse. We can add two counting numbers together, and we do not need to pay attention to the order of these whole numbers. But, for subtraction, we have to subtract the smallest counting number from the largest counting number.

If your talking about a line graph like my 4th grader uses, you can easily do add/sub as you simply count up or down the line.

Just be confident you'll do fine and you'll know
