Subtracting integers

[joannamartinez]

I need help with this problem too please. I need to subtract -3.4 - (-7.6). My formula is 7.6 - 3.4= -4.2. Is this correct? Please advise. Thank you.

I need to subtract -3.4 - (-7.6). My formula is 7.6 - 3.4= -4.2

First, those are NOT integers; integers are whole numbers.

2 consecutive minuses make a plus; example: -(-2) = 2

7.6 - 3.4 = 4.2 , NOT -4.2 :shock:

integers are whole numbers

The set of Whole numbers is a subset of the set of Integers.

Therefore, we can say that all Whole numbers are Integers, but we cannot say that all Integers are Whole numbers.
