10 - (- 3) = 10 + 3 = 13
A quick check is to ask " How many steps from (-3) to 10 on the number line?"
The answer to this is 13 steps to the right , giving an answer of 13

(+10) - (-3) = +13

Since the process is subtraction, we just change the sign of the number to be subtracted (-3) to positive (+3) then proceed to addition.
