Types of Numbers
1. *Natural Numbers*: 1, 2, 3, ...
#NaturalNumbers
2. *Whole Numbers*: 0, 1, 2, 3, ...
#WholeNumbers
3. *Integers*: ..., -3, -2, -1, 0, 1, 2, 3, ...
#Integers
4. *Rational Numbers*: Numbers that can be expressed as a fraction (e.g., 1/2, 3/4)
#RationalNumbers
5. *Irrational Numbers*: Numbers that cannot be expressed as a fraction (e.g., π, e)
#IrrationalNumbers
6. *Real Numbers*: The set of all rational and irrational numbers
#RealNumbers
7. *Complex Numbers*: Numbers that have both real and imaginary parts (e.g., 3 + 4i)
#ComplexNumbers

Properties of Numbers
1. *Commutativity*: The order of numbers does not change the result (e.g., 2 + 3 = 3 + 2)
#Commutativity
2. *Associativity*: The order in which numbers are grouped does not change the result (e.g., (2 + 3) + 4 = 2 + (3 + 4))
#Associativity
1. *Distributivity*: Numbers can be distributed over addition (e.g., 2(3 + 4) = 2(3) + 2(4))
#Distributivity

Operations with Numbers
1. *Addition*: The process of combining numbers (e.g., 2 + 3 = 5)
#Addition
2. *Subtraction*: The process of finding the difference between numbers (e.g., 5 - 3 = 2)
#Subtraction
3. *Multiplication*: The process of repeated addition (e.g., 2 × 3 = 6)
#Multiplication
1. *Division*: The process of sharing numbers into equal parts (e.g., 6 ÷ 3 = 2)
#Division

Other Important Concepts
1. *Place Value*: The value of a digit depending on its position (e.g., 123, where 1 is in the hundreds place)
#PlaceValue
2. *Rounding Numbers*: Approximating numbers to a certain place value (e.g., rounding 123.456 to 123.46)
#RoundingNumbers
3. *Estimation*: Approximating numbers or calculations (e.g., estimating 123 × 456 as 50,000)
