Let's remember the law:
Let's think about which number we need to multiply by 6 to get 12:
Now let's put the numbers together with the appropriate sign as written in the law above, as follows:
What will be the sign of the result of the next exercise?
\( (-2)\cdot(-4)= \)
Remember the sign rules: negative × positive = negative. Since (-6) is negative and the result (-12) is negative, the missing factor must be positive to make this work!
Use this pattern: same signs = positive, different signs = negative. Since (-6) and (-12) are both negative, they have the same sign, so the missing factor is positive.
No! The signs are part of the numbers and affect the final answer. Always work with the complete numbers, including their signs, from the beginning.
Check your work: (-6) × (-2) = +12, not -12! Remember that negative times negative equals positive. The correct answer is +2.
Always substitute your answer back into the original equation. If (-6) times your answer equals -12, then you're correct. This is the best way to catch sign errors!
