You can't just say that p+q= 13 and p-q= 5, because there are multiple ways to get 65. You can also do 0,65 times 100 and that gives you 65. I learnt this at school, but why does this give you the right answer? I don't understand...
@xanderthedev because 0.65 is a decimal value and 100 is not. So if you can find two decimal values that will give us 65, does two values will give us the answer we got in the video....🤗

P + q is greater than p - q, therefore p+q will take the bigger value while p-q will take the smaller value....
But why can't you use 0.65 and 100?

go study and uninstall UA-cam
I immediately see 81-16=65 and m=4.
Thank you 😊❤❤❤
