Algebraic expressions are a way of expressing numbers without describing their real values using letters or alphabets. The fundamentals of algebra taught us how to use letters to express an unknown value. Variables are the letters used in this equation. Variables and constants can both be used in an algebraic expression. A coefficient is any value that comes before a variable and is multiplied by it. An algebraic expression is a statement that contains variables, constants, and algebraic operations (addition, subtraction, etc.). Terms combine to form expressions.
Examples: • x²-4x+4 • x+y • x²-9 • 12y
Types of Algebraic Expression
• Monomial Expression- type of an algebraic expression which has only one term. Examples: 2xy, 4n, 3y
• Binomial Expression- type of an algebraic expression which has two terms and it is connected by a mathematical symbols + and -. Examples: 2x-7, 3y+10, x²-16
• Trinomial Expression- type of an algebraic expression that has three terms and it is connected by a mathematical symbols + and -. Examples: x²+6x+9, x²+4x+4, y²+8y+16.
Solving Algebraic Expression Examples: • 2x+ 24= 122 Subtract 24 in both sides to find the value of the variable x. 2x+24-24= 122-24 2x= 98, divide both sides by 2 2x÷2= x, 98÷2= 49 x= 49 • 5y-40= 75 Add 40 in both sides to find the value of the variable y. 5y-40+40= 75+40 5y= 115, divide both sides by 5 5y÷5= y, 115÷ 5= 23 y= 23
Translating Mathematical phrase into an Algebraic Expression
In translating mathematical phrase into an algebraic expression we need to understand the phrase or sentence well. Look for important words or words that we need to remember in order for us to translate the phrase or sentence into algebraic expression or equation easily. If the words are more than, sum, total, and added the mathematical symbol is +. If the words are diminished, minus, less than, and difference the mathematical symbol is -. If we remember the important words translating the phrase into algebraic expression will be easy.

Solving Algebraic Expression
Examples:
• 2x+ 24= 122
Subtract 24 in both sides to find the value of the variable x.
2x+24-24= 122-24
2x= 98, divide both sides by 2
2x÷2= x, 98÷2= 49
x= 49
• 5y-40= 75
Add 40 in both sides to find the value of the variable y.
5y-40+40= 75+40
5y= 115, divide both sides by 5
5y÷5= y, 115÷ 5= 23
y= 23
