It is hard to say one law is specifically used "most" in algebra. However, it is amazing just how useful the reflexive property is. Reflexive property: a=a The property states that any number equals itself and is necessary for most other properties.
Algebra can be used to solve for an unknown value in Graham's Law formula. The Grahams law formula can use algebra for solving for an unknown value in the formula.
As by "who" i assume you mean what profession. Algebra is used a lot in banking, economics, and doctors who need formulas. But overall algebra is mostly used by college leveled advanced algebra teachers.
no so much as laws, many different properties are used in algebra. the most dominant one is obviously what is known as the golden rule. it states that in an equation, both side of the equation most always be balanced, so if an operation is made to one side of the equation, the same operation must be done to the other
Algebra is used almost aspect of life. From the the simple y=mx equation to ratios everything is used. The most common example I see is the use of ratios at the grocery store. X price/A size=Y price/B size, to see which is the better deal. Also, law enforcement uses algebra to recreate accidents to serve justice.
a=b
Algebra is used for mathematics
It is called a variable. x is the most used variable.
'Part' is not a term used in Algebra.
The most used law of motion is F=ma, the 2nd law of motion.
in algebra class, in science, physics, and technology.
Algebra is used all the time. Many equations can be created for many things, and it's all thanks to algebra. Physics, Engineering, Computers, and most other technical professions require algebra, as well as higher mathematics. For someone who plans not going into the technical professions, basic things such as balancing your checkbook, and dealing with taxes often require atleast some knowledge of algebra.
Algebra is a subject most students learn, then never use again, because they don't see the many ways it can be used. Some of the world's greatest mathematicians did not use algebra. Algebra, for some, is like trying to learn multiplication tables for the alphabet.
