15+(-2) *
your answer
-8+10 *
your answer
11+(-3) *

Explanation:

Step1: Calculate \(-3\times(-5)\)

When multiplying two negative numbers, the result is positive. So \(-3\times(-5)=15\).

Step2: Calculate \(9+(-12)\)

Adding a negative number is like subtracting its absolute value. So \(9+(-12)=9 - 12=-3\).

Step3: Calculate \(-6+(-10)\)

Adding two negative numbers, we add their absolute values and keep the negative sign. So \(-6+(-10)=-(6 + 10)=-16\).

Step4: Calculate \(15+(-2)\)

Adding a negative number is like subtracting its absolute value. So \(15+(-2)=15 - 2 = 13\).

Step5: Calculate \(-8 + 10\)

Subtracting the smaller absolute value from the larger one and taking the sign of the number with the larger absolute value. Here \(10-8 = 2\), and since \(10\) is positive, the result is \(2\).

Step6: Calculate \(11+(-3)\)

Adding a negative number is like subtracting its absolute value. So \(11+(-3)=11 - 3 = 8\).

Answer:

\(-3\times(-5)=15\)
\(9+(-12)=-3\)
\(-6+(-10)=-16\)
\(15+(-2)=13\)
\(-8 + 10=2\)
\(11+(-3)=8\)
