I'm not sure by the way you layed out the question but, 2. 5(14-23)+8/2. First you have to use distributive method so 5 times 14 equals 70 and 5 times 23 equals 115 so that means it's 70-115+8/2. Then 8/2 equals 4 so 70-115+4 so then 70-115 equals negative 35. That is -35+4 so the answer is -31 or in other words negative thirty one.
I am not sure if I helped out but I tried my best
