Study Notes
Basic Definitions
- Division is the process of splitting a quantity into equal parts or groups.
- It is the inverse operation of multiplication.
- The dividend is the number being divided.
- The divisor is the number that divides the dividend.
- The quotient is the result of the division.
- The remainder is the amount left over after dividing.
Division Algorithm
- The division algorithm is a method for dividing one integer by another to find the quotient and remainder.
- It guarantees that there exist unique integers
qandrsuch thata = bq + r, where0 ≤ r < b, anda,b,q, andrare integers. -
ais the dividend,bis the divisor,qis the quotient andris the remainder.
Division with Remainders
- When a number cannot be divided evenly, a remainder arises.
- The remainder is always less than the divisor.
- Understanding remainders is crucial in various applications, such as distributing items into groups.
Division of Whole Numbers
- Used extensively in everyday calculations and problem-solving.
- Division of whole numbers follows a specific set of rules to arrive at the correct quotient and remainder.
- Long division is a common method for dividing multi-digit numbers.
Division of Decimals
- Involves dividing numbers with decimal points.
- The decimal point in the divisor must be moved to the right to make the divisor a whole number.
- The decimal point in the dividend must be moved the same number of places to the right.
- The decimal point in the quotient needs to be placed directly above the decimal point in the dividend after the decimal point is moved.
- Zeros may need to be placed as placeholders in the dividend or quotient when necessary.
Division of Fractions
- Involves dividing one fraction by another.
- The division of fractions is calculated by multiplying the dividend by the reciprocal of the divisor.
- Proper understanding of the rules of multiplying fractions is important in this process.
Division by Zero
- Division by zero is undefined and a mathematical error.
Applications of Division
- Distribution or sharing of items into groups.
- Calculating averages and rates.
- Measurement and comparison of quantities.
- Solving word problems in various contexts.
- Finding ratios and proportions.
