The formal addition rule is P(A or B) = P(A) + P(B) - P(A and B). A good example from the related link, from the addition rule section is: ; Suppose we wish to find the probability of drawing either a king or a spade in a single draw from a pack of 52 playing cards. ; We define the events A = 'draw a king' and B = 'draw a spade'. ; Since there are 4 kings in the pack and 13 spades, but 1 card is both a king and a spade, we have (same formula as above in symbols): : = 4/52 + 13/52 - 1/52 = 16/52 ; So, the probability of drawing either a king or a spade is 16/52 (= 4/13).

An Algorithmic solution is a solution that involves a series of actions/steps. For example, baking a cake. A Heuristic solution is a solution that requires knowledge, experience, and sometimes trial and error. For example, buying the best stock. While some problems require only one type of solution, most problems require a combination of the two different types of solutions.
-2 is the additive inverse of +2
Joint probability is the probability that two or more specific outcomes will occur in an event. An example of joint probability would be rolling a 2 and a 5 using two different dice.
In theoretical probability, the probability is determined by an assumed model (for example, the normal distribution). (compare with empirical probability)

You can find LOTS of problems, often with solution, by a simple Google search, for example, for "calculus problems". Here is the first hit I got:https://www.math.ucdavis.edu/~kouba/ProblemsList.html
By definition, an equation has a solution. The word comes from "equal". Some mathematical problems do not have solutions. For example, 1/0 = X is a problem with no solution. You know, in this example that there is no solution because of the "divide by zero" rule. Most insoluble problems are insoluble because of some rule that keeps you from moving ahead.
The additive identity property states that any number plus zero is that number. For example: 5 + 0 = 5.
You can find some of these solutions online. An example would be the volume of frustum or a similar problem.

The additive inverse for a number is its negative value. The sum of an integer and its additive inverse is zero. For the example (5), the additive inverse would be (-5).
-2 is the additive inverse of +2
The additive inverse of a number is that which when added to the number gives 0. If n is a number then the additive inverse of it (-n) is that number such that: n + -n = 0 For example, the additive inverse of '4' is '-4'.
The probability of event A occurring given event B has occurred is an example of conditional probability.
Joint probability is the probability that two or more specific outcomes will occur in an event. An example of joint probability would be rolling a 2 and a 5 using two different dice.
Zero. For example, the additive inverse of 5 is -5, and 5 + (-5) = 0.
