Study Notes
- Basic arithmetic encompasses the fundamental operations of addition, subtraction, multiplication, and division. These operations form the foundation for more complex mathematical concepts.
Addition
- Addition combines two or more numbers (addends) to obtain a single sum.
- The commutative property applies: a + b = b + a.
- The associative property applies: (a + b) + c = a + (b + c).
- Zero is the additive identity: a + 0 = a.
Subtraction
- Subtraction finds the difference between two numbers (minuend and subtrahend).
- The minuend is the number from which another number is subtracted.
- The subtrahend is the number that is subtracted.
- Subtraction is the inverse operation of addition.
- Subtraction is not commutative: a - b ≠ b - a.
Multiplication
- Multiplication is a shorthand for repeated addition.
- It involves multiplying two or more numbers (factors) to obtain a product.
- The commutative property applies: a × b = b × a.
- The associative property applies: (a × b) × c = a × (b × c).
- Multiplication by 1 yields the original number: a × 1 = a.
- Multiplication by 0 results in 0: a × 0 = 0.
Division
- Division distributes a quantity into equal parts.
- It involves finding how many times one number (divisor) goes into another number (dividend).
- The result is the quotient.
- The dividend is the number being divided.
- The divisor is the number by which the dividend is divided.
- Division is the inverse operation of multiplication.
- Division by zero is undefined.
Fractions
- Fractions represent parts of a whole.
- A fraction is written as a/b, where 'a' is the numerator and 'b' is the denominator.
- The numerator indicates the number of parts considered.
- The denominator indicates the total number of equal parts in the whole.
- Fractions can be proper (numerator smaller than denominator), improper (numerator greater than or equal to denominator), or mixed (a combination of a whole number and a proper fraction).
- Equivalent fractions represent the same part of a whole but use different numerators and denominators.
- Operations on fractions involve adding, subtracting, multiplying, and dividing fractions according to specific rules.
- Simplification often involves reducing a fraction to its lowest terms by dividing both numerator and denominator by their greatest common divisor.
- Addition and subtraction of fractions require a common denominator.
- Multiplication of fractions involves multiplying the numerators and multiplying the denominators.
- Division of fractions involves inverting the divisor and multiplying.
