Luisa claims that when she subtracts two negative integers, the result is always positive. Is she correct?

#-3-(-7)=-3+7=4#

So no, it is not correct to say that anytime two negative integers are subtracted the result is positive.

Explanation:

Let's test it!

We have two negative integers, let's say #-3 and -7#.

Let's first subtract #-3# from #-7#:

#-7-(-3)=-7+3=-4#

now let's do it the other way and subtract #-7# from #-3#:

#-3-(-7)=-3+7=4#

So no - it is not correct to say that anytime two negative integers are subtracted the result is positive.

No she is not correct

Explanation:

By example: Suppose we have: #" "-4-(-1)#

This is the same as:#" "-4+1=-3#

The solution in this case is negative.

This contradicts the statement in the question.

So the statement: "subtracts two negative integers, the result is always positive" is false
