(always start out with the bigger number, then subtract the smaller number to find the answer and add the bigger numbers -/+ to it. )
How to solve:
5+-8
you take eight and subtract five, and get three. then you add a negative (-) to the three because there were more negatives than posotives in this case. so the answer is: -3.
-4+10
You take 10 and subtract 4 and get 6.
4-9
You take 9 and take away 4 to get 5. then add a (-), in this case they were both posotive #s but the bigger number was being subtracted so the number was negative.
-8-(-9)
the rule for subtracting negatives is just to add the two negative numbers together to get an even bigger negative.
