Answer:
(4,-7) = 11 or 9
(-5,5) = 10 or 8
Explanation:
you only have to count the numbers between 4, -7 and -5,5 (I believe) and that´s the answer, it also depends if you want to count the numbers that you are giving, for example, if you include the 4 and the -7 in the first one, the answer will be 11, but if you have to count only the numbers between them, the answer will be 9, hope it helps :)
