Only like terms can be subtracted or added in algebraic expressions.
the reason you use letters in algebraic expressions is because you don't know the number so a letter replaces it.
I think it is important because you need to know it when you get older.
Variable is any letter used in an algebraic expression, and can vary (change form) to be any number, and one variable means the same number in any single algebraic expression. Usually algebra is simplifying the expression or equation until you know what the variable is equal to.
Learning the expressions is the same thing as learning your multiplication tables - it helps you to understand algebra. And algebra allows you to understand things like logic, statistics, and all sorts of calculations where you don't know enough numbers to do a straight addition or multiplication or subtraction or division.
Replace each variables in the algebraic expression by its [known] value and calculate the value (ie evaluate) of the algebraic expression.
Yes!!! What do you want to know about simplifying trig. expressions.

Algebraic expressions are useful for translating problems into the language of mathematics. An algebraic expression for the problem "6 times the sum of 4 and y" would be: 6(4+y) = 24 + 6y.

You need to find the common denominator in order to add or subtract them. You can only add or subtract "like things" and by finding a common denominator you make both rational expressions into things that can be added or subtracted.
An algebraic geometer is a mathematician who specializes in algebraic geometry.
Karnaugh maps are used for simplifying Boolean expressions and optimizing logic circuits. Understanding how to use Karnaugh maps can help you reduce the number of terms in a Boolean function, resulting in simpler and more efficient circuits. It is a valuable tool in digital circuit design and can improve logic design skills.
