Yes, though many people understand it better by saying, "Adding an opposite," rather than "Adding a negative."
As examples,
5 - 3
= 5 + (-3)
= 2
[Subtracting means to add the opposite... instead of subtracting (+3), you add (-3).]
5 - (-3)
= 5 + (+3)
= 8
[Again, subtracting means to add the opposite... instead of subtracting (-3), you add (+3).]
Yes, for 5 - (-3), you're adding the negative of (-3)... technically making the problem
5 + -(-3) = 5 + 3 = 8.
You add positive three either way, but saying "Adding an opposite" seems easier for a student to understand.

Not exactly. Subtraction is the same as 'addition of the opposite'.
If you said 9 minus 8, your statement holds up because it is the same as 9 + negative 8.
However, 9 minus negative 8, [9 - (-8)], should be read as 9 plus the opposite of negative 8.
In fact, cementing this idea in your head will be very, very helpful as the algebra questions get harder and harder. Another to remember is to turn division into 'times the recipricol of'.

Yes. Subtraction is nothing but adding negative number

I don't know what number I am I thought I would reemphasize it.
