What can you subtract from 7 so that that the number is even but the number subtracted cannot be an odd?
7 is an odd number. If you subtract an odd number minus an even number, you will always get an odd number. There is no way to avoid this.
Why is the product of two odd numbers odd?
Let me show this to you by an example : Suppose we wish to multiply 3 and 7. Product or Multiplication by any device is actually carried by the process of addition of 3 seven times, i.e. 3+3+3+3+3+3+3 = 21. Because the two numbers are odd, the result is always odd. To Summarize, addition of an odd number(i.e. 3) to itself an odd number of times(i.e. 7) always results in an odd number. The product of an even and an odd number always results in an even number because addition of even number any number of times is always even and an odd number added to itself an even number of times also results in an even number. For ex. 7*2 = 14, here 7(odd number) is added 2(even number) times, i.e. 7+7=14 which is even.
Is the number 43577 an a even number or an odd number?
43577 is a odd number because the end of the number is 7
Do you have to have a odd number if you are dividing by 7?
No. 14, an even number, is divisible by 7.
The sum of an even and odd number?
Lets find out.2 + 3 = 5 (Odd)4 + 7 = 11 (Odd)12 + 13 = 25 (Odd)So it appears that the sum of an even and odd number is an odd number.
