Why can't 3 odd numbers equal 50?
3 odd numbers can't be equal to 50 because: odd number + odd number = even number even number + odd number = odd number thus, adding 3 odd numbers will always give a sum which is an odd number too even number.
Is 2468101213 an even or odd number and why?
It is an odd number because its last digit of 3 is an odd number
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.
Why is when you subtract 1 from the square of an odd number it is even?
An odd number multiplied by another odd number will always equal an odd number. Therefore odd2 = odd x odd = odd number. eg 32 = 3 x 3 = 9. Take away 1 and you will have on even number.
Use a diagram to illustrate that the sum of an odd number and an odd number is an even number?
3 + 3 = 6
