solve the following problems.

1. $7 + (-8) =$
2. $-7 - 7 =$
3. $-2 + 5 =$
4. $1 - (-9) =$
5. $-9(6) =$

Explanation:

Step1: Assign integer to gain

Gaining is positive: $+5$ or $5$

Step2: Assign integer to below sea level

Below sea level is negative: $-50$

Step3: Assign integer to withdrawal

Withdrawal is negative: $-100$

Step4: Assign integer to loss

Loss is negative: $-45$

Step5: Order negative integers

Larger negative = smaller value: $-18 < -16 < -15 < -12$

Step6: Add positive and negative

$7 + (-8) = 7 - 8 = -1$

Step7: Subtract from negative

$-7 - 7 = -14$

Step8: Add negative and positive

$-2 + 5 = 3$

Step9: Subtract negative (add positive)

$1 - (-9) = 1 + 9 = 10$

Step10: Multiply negative and positive

$-9 \times 6 = -54$
