Determine the resulting sign of the following exercise:
When there is no minus or plus sign before the numbers, we usually assume that these are positive numbers as shown below:
(+1/4)*(+1/2)=
The dot in the middle represents multiplication:
So the question in other words is - what happens when we multiply two positive numbers together?
We know that two positive integers when multiplied result in a positive integer:
Therefore the answer is "positive".
Positive
What will be the sign of the result of the next exercise?
\( (-2)\cdot(-4)= \)
Look for the minus sign (-)! If there's no minus sign in front, the fraction is positive. For example, is positive, but is negative.
The result is always positive! Just like with whole numbers: positive × positive = positive. The size doesn't matter - even tiny fractions follow this rule.
No! Whether a fraction is or , if there's no negative sign, it's positive. Size and sign are completely different things.
Then you'd get a negative result! Remember: positive × negative = negative. For example, would be negative.
