a^2-2ab+b^2 We multiply each term as follows a(a)+(a)(-b)+(-b)(a)+(-b)(-b) a^2-ab-ba+b^2 a^2-ab-ab+b^2 a^2-2ab+b^2 Or you can use the FOIL method. This is the same thing but just visualizing differently. FOIL stands for First Outside Inside Last First multiply the first terms in (a-b)(a-b) a(a)=a^2 Now add the products of the Outside and Inside terms a^2+(a)(-b)+(-b)(a)=a^2-2ab Finally we add. Not sure if you are familiar with the arrow function syntax. Just in case, here's a short explanation: (a, b) => a - b is a shortcut notation for:. function (a, b){ return a - b; } Function sort takes a comparison function as a parameter. This is what the sorting algorithm uses repeatedly to compare two elements in the array and decide which one goes to the left of the array and which goes. - Mathematics Stack Exchange In boolean algebra, why is a+a'b = a+b?

Commutative Laws The "Commutative Laws" say we can swap numbers over and still get the same answer.. when we add: a + b = b + a Example:. or when we multiply: a × b = b × a Example: Percentages too! Because a × b = b × a it is also true that: a% of b = b% of a Example: what is 8% of 50 ? 8% of 50 = 50% of 8 = 4 Why "commutative ". ? Otherwise, the result of the binary operation is converted to the type of the left-hand variable, subjected to value set conversion (§5.1.13) to the appropriate standard value set (not an extended-exponent value set), and the result of the conversion is stored into the variable. So your expression does: a^=b^=a^=b; evaluate a. The B-1 is a long-range, multi-mission and supersonic conventional bomber, according to the Air Force. It has served the Air Force since the 1980s and the United States eliminated the nuclear.
