Study Notes
Odd and Even Numbers
- Odd numbers cannot be divided evenly by 2; examples include 1, 3, 5, 7, etc.
- Even numbers are divisible by 2; they include 0, 2, 4, 6, and so on.
Multiples and Products
- Multiples of a number are generated by multiplying that number by integers; for example, multiples of 5 include 5, 10, 15, 20, etc.
- The smallest multiple of 5 is 5 itself, while 10 is the second smallest.
Key Products
- The product of two numbers is the result of their multiplication; for instance, 5 x 2 = 10.
- Important mathematical fact: 2 x 3 x 5 = 30 shows how to combine numbers to achieve greater products.
Factorization
- A number’s factors are the integers which divide it evenly; for instance, 21 is a factor of 315.
- The expression 30 can be factored as 2 x 3 x 5, which showcases the prime factorization of the number.
Number Sequences
- A sequence can include both odd and even numbers, and they can alternate based on their multiplicative properties.
- Exploring multiples between two numbers (like 18 and 24) can illustrate common multiples.
Identification of Numbers
- Identifying the first two-digit odd and even numbers: The first two-digit odd number is 11, and the first two-digit even number is 10.
- The last digit of an odd number is always 1, 3, 5, 7, or 9; this helps in recognizing odd numbers quickly.
General Principles
- Multiplication can yield both even and odd products depending on the factors used; for example, multiplying an even number by an odd number always results in an even product.
- Patterns within number sets can aid in predicting subsequent numbers in a sequence, especially in terms of parity (odd/even nature).
