In high school, algebra is considered a painful slog, and most students hate it. It always has too many rules and no enough answers. You need to realize that there’s more to algebra than just addition and subtraction.
Algebra is important because it helps us understand numbers. It’s how we add two and two or find the square root of two… it all leads up to solving real-world problems like calculating taxes, etc. This article will cover why algebra is important and why we should embrace it in our day-to-day lives.

What Is Algebra?
Algebra is a branch of Mathematics that becomes important in middle school or high school. In the Mathematical field of algebra, letters are used in place of numbers. They’re used to solve problems that might otherwise take a long time to figure out.
You can think of algebra as the opposite of arithmetic, where arithmetic is basically adding and subtracting numbers. Algebra is used to solve more complex problems–ones that have variables in them.

The General Algebraic Equations
- a2 – b2 = (a – b)(a + b)
- (a + b)2 = a2 + 2ab + b2
- a2 + b2 = (a + b)2 – 2ab
- (a – b)2 = a2 – 2ab + b2
- (a + b + c)2 = a2 + b2 + c2 + 2ab + 2bc + 2ca
- (a – b – c)2 = a2 + b2 + c2 – 2ab + 2bc – 2ca
- (a + b)3 = a3 + 3a2b + 3ab2 + b3 ; (a + b)3 = a3 + b3 + 3ab(a + b)
- (a – b)3 = a3 – 3a2b + 3ab2 – b3 = a3 – b3 – 3ab(a – b)
- a3 – b3 = (a – b)(a2 + ab + b2)
- a3 + b3 = (a + b)(a2 – ab + b2)
- (a + b)4 = a4 + 4a3b + 6a2b2 + 4ab3 + b4
- (a – b)4 = a4 – 4a3b + 6a2b2 – 4ab3 + b4
- a4 – b4 = (a – b)(a + b)(a2 + b2)
- a5 – b5 = (a – b)(a4 + a3b + a2b2 + ab3 + b4)
- If n is a natural number an – bn = (a – b)(an-1 + an-2b+…+ bn-2a + bn-1)
- If n is even (n = 2k), an + bn = (a + b)(an-1 – an-2b +…+ bn-2a – bn-1)
- If n is odd (n = 2k + 1), an + bn = (a + b)(an-1 – an-2b +an-3b2…- bn-2a + bn-1)
- (a + b + c + …)2 = a2 + b2 + c2 + … + 2(ab + ac + bc + ….)
- Laws of Exponents (am)(an) = am+n ; (ab)m = ambm ; (am)n = amn
Types of Algebraic Expressions
1. Monomial Expression
Just as the name implies monomial expressions are just a single variable. For example: 5xy. This is called a monomial because it only has one variable.
2. Binomial Expression
A binomial expression is an algebraic expression with two terms that are not the same. They could be the same variable, but they’re not. xy + yz, 6xz – 2yz)
- 4x – 3y = 4(x)-3(y)
- 8x + 11y = 8(x)+11(y)
There are many different ways to express various sums of binomials, but they all derive from the same logic.
3. Polynomial Expression
A polynomial is an expression that has many terms with non-negative integral exponents of a single variable. For example,ax + by + ca, x3 + 2x + 3
There are also other types of algebraic expressions;
1. Numeric Expression
It is the simplest form of algebraic expression. It can be a single number or a combination of numbers with constants but contains no variables. For example 9+2, etc
2. Variable Expression
An expression that uses variables, numbers, and an operation to define the expression is referred to as a variable expression. For, example 3x + z, etc
10 Reasons Why Algebra is Important
