By doing this it aligns all the place values so you can clearly add or subtract the correct place values and get a correct answer. You might say it is an organization technique. Of course if you use a calculator, this is not necessary.

What will be the difference when subtracting two integers with different signs?

Subtracting: Positive - Negative = Positive Negative - Positive = Negative No that is not the way it goes. It is positive+negetive=either counting on which integer is bigger negative+negative=positive positive+positive=positive positive x negetive=negative negative x postitve= negative negative/positive=negative positive/negative=negetive thanks The top is right though because subtracting a negative is like adding so you could never get a negative and subtracting from a positive from negative will always be a negative. The question was for integers with different signs so you don't need to do "positive + positive"


What do you do when subtracting a positive and a negative?

If you subtract a negative from a positive, add both of their absolute values. If you subtract a positive from a negative, add both of their absolute values and multiply by negative one.


A negative plus a negative is positive?

No a negative plus a negative is not a positive answer. example. -5+-2=-7 but if you are subtracting a negative number from a negative, then the second negative number would become a positive. example. -5 - -2= -5+2= =-3
