The sum of two numbers is less than $120$ with he first number is bigger than the second. The differences (subtraction) between the two numbers is $60$. Find the lowest result of multiplication between the two numbers.
This is an easy question, but I can't seemed to solve this one. Anyway, from the question we obtained:
$$ a+b<120$$ $$a-b=60$$ And $$a>b$$
As if it normal equations, I would have solve them easily. Any suggestions?
