Solution
a) Sum of -30 and 17: Step 1: Identify the numbers: -30 and 17. Step 2: Since one number is negative and the other is positive, subtract the smaller absolute value from the larger absolute value. Step 3: |-30| = 30 and |17| = 17, so 30 - 17 = 13. Step 4: The result takes the sign of the number with the larger absolute value, which is -30. Step 5: Therefore, the sum is -13.
b) Sum of -42 and -15: Step 1: Identify the numbers: -42 and -15. Step 2: Since both numbers are negative, add their absolute values. Step 3: |-42| = 42 and |-15| = 15, so 42 + 15 = 57. Step 4: The result is negative because both numbers are negative. Step 5: Therefore, the sum is -57.
c) Sum of -13 and -16: Step 1: Identify the numbers: -13 and -16. Step 2: Since both numbers are negative, add their absolute values. Step 3: |-13| = 13 and |-16| = 16, so 13 + 16 = 29. Step 4: The result is negative because both numbers are negative. Step 5: Therefore, the sum is -29.
d) Multiplication of -8 by 6: Step 1: Identify the numbers: -8 and 6. Step 2: Multiply the absolute values of the numbers. Step 3: |-8| = 8 and |6| = 6, so 8 * 6 = 48. Step 4: The result is negative because one number is negative and the other is positive. Step 5: Therefore, the product is -48.
e) Multiplication of -11 by -: Step 1: Identify the numbers: -11 and -. Step 2: Multiply the absolute values of the numbers. Step 3: |-11| = 11 and |-| = , so 11 * = . Step 4: The result is positive because both numbers are negative. Step 5: Therefore, the product is .
