Hi;

Welcome to the forum.

In mathematics, you don't understand things. You just get used to them.
Probability is the most important concept in modern science, especially as nobody has the slightest notion what it means.
90% of mathematicians do not understand 90% of currently published mathematics.

Bobbym and anonimnystefy, you are both correct!
Now, second equation using PEMDAS:
Make 75 using the numbers 5 5 3.
Use the operations + - * / 2 3.
