I don't understand what has happened in the second to last step here.
Yes sorry I should have stated that k has to be equal to or larger than 5. I didn't mean to try to argue with you. It's just that I'm trying to understand what is happening in the second to last step in the working. I can't see how the expression on the left is converted into an equality and then what it means to have an equality there.
I'm sorry I don't understand
how does How does an integer equal an equality?
how do you get from this line to the last?
How does this relate to the original working I posted?
I'm trying to understand how we go from an integer expression to an equality and then back again and how I am supposed to understand the meaning of this equality. To put it simply one equals a number and the other is true or false so how can they be equal?
Thanks.
Well an equality has a Boolean value that is either true of false. So the left hand side of the equation must be equal to one of two values. True of False. The expression on the right hand side is a number. How can you equate them?
You obviously can because that is what you are doing I just don't understand how you are doing it.
