Fill in the corresponding sign for the following question
Let's consider what we would need to multiply by a positive in order to obtain a negative number.
Let's remember the rule:
Therefore, the answer will be:
Determine the correct answer for the following exercise:
\( (-2)\cdot(-4)= \)
Use this simple pattern: Same signs = Positive, Different signs = Negative. So (+) × (+) = (+) and (-) × (-) = (+), but (+) × (-) = (-) and (-) × (+) = (-).
Because 4 × (+3) = +12, not -12! Since we need a negative result (-12), and 4 is positive, the unknown number must be negative to get a negative product.
Look at what you're given! We know 4 is positive and the result is negative. Since different signs give negative results, the missing number must be negative.
Simply multiply: 4 × (-3) = -12. If this matches the right side of the equation, you're correct! Always substitute your answer back to verify.
Yes! Division follows the same pattern: same signs give positive results, different signs give negative results. So (-12) ÷ 4 = -3 and (-12) ÷ (-4) = +3.
