Have a nice break!
Thank you! I am much more informed now. :)
You use variables.
x/2=45-20
x/2=25
x/2*2=25*2
x=50
I got confused if order mattered, but thank you!
39 because the square of 400 is 20, so we have to be consecutive, so 20+19=39
I think it means something like the same center but I am not sure, so can anyone confirm this for me?
