Do the rest of them (multiply, divide, subtract)

Question

An even number + an even number = an even number
An odd number + an odd number = an even number
An even number - an odd number and an odd number - an even number = to an odd number.

What are the rest?

Answer 1

Sure! Here are the rules for multiplication, division, and subtraction regarding even and odd numbers:

Multiplication:

1. An even number × an even number = an even number
2. An even number × an odd number = an even number
3. An odd number × an odd number = an odd number

Division:

1. An even number ÷ an even number = an even number (if the result is an integer)
2. An even number ÷ an odd number = an even number (if the result is an integer)
3. An odd number ÷ an odd number = an odd number (if the result is an integer)
4. Note: Division can be tricky because it does not necessarily yield integers, especially if the divisor does not perfectly divide the dividend.

Subtraction (already provided):

1. An even number - an even number = an even number
2. An odd number - an odd number = an even number
3. An even number - an odd number = an odd number
4. An odd number - an even number = an odd number

These rules generally hold true in basic arithmetic for even and odd integers.
