When you have a negative and your subtracting it to a number so for example 7-(–3)=10 because you can do KCC which stands for “keep change change” so u would keep the positive 7 the same but change the minus sign to plus and (-3) to a positive three. Hope that helps! :)
<span>If both signs are positive, the answer will be positive. Example: 14 - (-6) = 14 + 6 = 20.If both signs are negative, the answer will be negative. ... <span>If the signs are different subtract the smaller absolute value from the larger absolute value.</span></span>Is what I found
... because you divide the time but the distance so for this question you divide 22.5 by 5 and that's your answer. do the same for every question! hope this helps.
