Mathematical Expressions 
Mathematical Operations are fundamental processes in mathematics that involve performing various calculations and manipulations on numbers or mathematical expressions. These operations include addition, subtraction, multiplication, and division. Understanding these operations is crucial for solving mathematical problems and equations.
Let's explore the four basic mathematical operations:
Addition (+):
Subtraction ():
Multiplication (×):
Division (÷):
When performing multiple mathematical operations in a single expression, it's essential to follow the order of operations (PEMDAS/BODMAS):
P: Parentheses (Brackets)
E: Exponents (Orders)
M: Multiplication
D: Division
A: Addition
S: Subtraction
Mathematical operations are often used in mathematical expressions and equations to solve realworld problems. Expressions may contain variables, constants, and operations.
Example: Solve for x in the equation: 3x + 5 = 11.
Subtract 5 from both sides to isolate 3x: 3x = 11  5 = 6.
Divide both sides by 3 to solve for x: x = 6 ÷ 3 = 2.
