What will be the sign of the result of the next exercise?
Let's remember the rule:
Therefore, the sign of the exercise result will be negative:
Negative
Determine the correct answer for the following exercise:
\( (-2)\cdot(-4)= \)
Think of multiplication as repeated addition. means adding -4 twelve times: -4 + (-4) + (-4)... = -48. You're adding negative numbers, so the result stays negative!
The order doesn't matter! gives the same result as . Different signs always produce negative results, regardless of which number comes first.
Use this simple pattern: Same signs = Positive (+ × + or - × -), Different signs = Negative (+ × - or - × +). Think 'opposites attract trouble' for different signs!
For determining the sign of the result, focus on the signs first! Once you know it's negative, then calculate and add the negative sign to get -48.
Count the negative signs! An even number of negatives gives positive, an odd number gives negative. For example: (-2) × (-3) × (-1) has 3 negatives (odd) = negative result.
