Choose numbers with a particular sum, difference, product, or quotient
Key notes :
Addition (Sum):
- The sum is the result of adding two or more numbers.
- Example: If you need a sum of 10, pairs can be (7 + 3), (6 + 4), (5 + 5).
Subtraction (Difference):
- The difference is the result of subtracting one number from another.
- Example: If you want a difference of 5, pairs can be (10 – 5), (8 – 3), (7 – 2).
Multiplication (Product):
- The product is the result of multiplying two numbers.
- Example: For a product of 12, pairs can be (3 × 4), (2 × 6), (1 × 12).
Division (Quotient):
- The quotient is the result of dividing one number by another.
- Example: For a quotient of 4, pairs can be (16 ÷ 4), (12 ÷ 3), (8 ÷ 2).
