Harry had 4 daughters. Each daughter had a brother. How many children does Harry have?
BTW, math only when time allows. I am desperately seeking to move out. I miss Cohen and daily math solving but life plus the fear of COVID-19 has paralyzed my life. I also may be let go from the job. You can understand how difficult life has become for me (and the world).
Here is what I found online:What is her reasoning?
I do agree there could be other answers. For example, suppose Harry had his 4 daughters with multiple women, and we make the distinction between full and half brothers, etc.
