How do you subtract negative numbers

Subtracting a negative number from a negative number—when you see the subtraction (minus) sign followed by a negative sign, turn the two signs into a plus sign. Thus, instead of subtracting a negative, you are adding a positive. So, – -5 becomes +5, and continue normally with the addition.For example - 39 - (-40) is the question you will change (-40) into (+40) and change the operation from subtraction to addition and do the problem same like addition
