Let's remember the law:
Let's think about which number we need to multiply by 12 to get 24:
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?
\( (-2)\cdot(-4)= \)
Because negative times positive equals negative! If we multiply , not positive 24. Since we need positive 24, the missing number must be positive.
Look at the operation symbol! Since we have multiplication (), we use the inverse operation which is division to find the missing factor.
That's totally fine! Not all multiplication problems have whole number answers. Just make sure to check your work by multiplying back to see if you get the original product.
Absolutely! You can write and solve by dividing both sides by 12. Both methods give the same answer: .
Understanding factor relationships helps with mental math, fraction work, and algebra later on. Plus, knowing that multiplication and division are inverse operations is a key math concept!
