5 7 + (-13) =
6 -4 - 16 =
7 3 - 11 =
8 -5(9) =
9 -32 ÷ 8 =
10 -56 ÷ (-7) =
11 -9 + (-9) =
12 -6 - (-8) =
13 11 - 15 =
14 -6(-12) =

Explanation:

Step1: Add positive and negative number

$7 + (-13) = 7 - 13 = -6$

Step2: Subtract from negative number

$-4 - 16 = -(4+16) = -20$

Step3: Subtract larger from smaller number

$3 - 11 = -(11-3) = -8$

Step4: Multiply negative and positive

$-5(9) = -5 \times 9 = -45$

Step5: Divide negative by positive

$-32 \div 8 = -\frac{32}{8} = -4$

Step6: Divide negative by negative

$-56 \div (-7) = \frac{-56}{-7} = 8$

Step7: Add two negative numbers

$-9 + (-9) = -9 -9 = -18$

Step8: Subtract negative (add positive)

$-6 - (-8) = -6 + 8 = 2$

Step9: Subtract larger from smaller number

$11 - 15 = -(15-11) = -4$

Step10: Multiply two negative numbers

$-6(-12) = -6 \times (-12) = 72$
