How do you subtract and add integers

Well ... it only depends what you're working with ...

If you're working with both numbers as positive move up (or move right on a number line). But if you're working with both numbers as negatives you would go downward (or move to the left on a number line) ... If you have opposite signs for the numbers you would have to subtract the number.

Remember⬇

Positive & Positive = Positive

Negative & Negative = positive (or negative ... it depends what you're working with)

Positive & Negative = Negative

Integers are whole numbers.

So subtracting 7-5 is 2

Adding the numbers 7+5 is 12

Subtraction is the différence between the two numbers.
