<u>Explanation:</u>
The sign of the product of any odd number of negative integers is positive because when two minuses are multiplied with each other, it will result in a positive number.
<u>For example:</u>
- -3 x -5
- => -1 x -1 x (3 x 5)
- => 1 x (3 x 5)
- => 15 (Which is positive)

Hello,
Let's be a the greatest number, b the smallest
Method 1:
a+b=37 ==>b=37-a
a*b=36==>a(37-a)=36
==> a²-37a+36=0
==>a²-36a-a+36=0
==>a(a-36)-(a-36)=0
==>(a-36)(a-1)=0
(a=36 and b=37-36=1) or (a=1 and b=37-1=36) but a>b ==>exclude
==>a-b=35
Method 2:
a*b=36
a+b=37 ==>(a+b)²=37²
(a+b)²-4ab=37²-4*36
==>a²+2ab+b²-4ab=1225
==>(a-b)²=35²
==>a-b=35 or a-b=-35 (to exclude since a>b)
