These are the basics that every student learns in their elementary school. Here is a brief of these operations. Addition: Sum of numbers (Eg. 1 + 2 = 3) These are symbols that is most commonly used in linear algebra. If x=y, x and y represent the same value or thing. If x≈y, x and y are almost equal. If x≠y, x and y do not represent the same value or thing. If x<y, x is less than y. If x>y, x is greater than y. If x≪y, x is much less than y. P(A) = n(A)/n(S) Where P(A) is the Probability of an Event. n(A) is the Number of Favourable Outcomes n(S) is the Total Number of Events. Fraction.
