Think of division as repeated subtraction. When you divide 7.5 by 3, you're asking "how many groups of 3 fit into 7.5?" Since both numbers are positive, the answer must be positive too!
Negative ÷ negative also equals positive! The rule is: same signs give positive results, whether it's (+) ÷ (+) or (-) ÷ (-).
Division gives negative results when the signs are different: positive ÷ negative = negative, or negative ÷ positive = negative.
No! You can determine the sign before doing any calculations. Just look at the signs of the numbers being divided and apply the sign rules.
