how would you explain how to do Inequalities? With negative numbers, and how to add and subtract ex: a+7<10+? how would that be solved .

You would isolate the variable to one side of the inequality.
A+7<10
A< 3
Whenever A is less than 3 the inequality is true.
If it were
A8 < 10
A < 18
At this point you would divide both sides by 1, when dividing by a negative with an inequality the inequality flips so the answer would like:
A > 18
