Compute: -3+9 Answer:

Identify Signs: Identify the signs of the two numbers to determine if they are negative or positive. We have -3 (negative) and +9 (positive). Since they have different signs, we will subtract the smaller absolute value from the larger one.Determine Absolute Values: Determine the absolute values of the numbers. The absolute value of -3 is 3, and the absolute value of 9 is 9. Now, subtract the smaller absolute value from the larger one: 9 - 3.Perform Subtraction: Perform the subtraction. Calculate: 9 - 3 = 6.Determine Sign: Determine the sign of the final answer. Since the larger absolute value was from the positive number (+9), the result will be positive.Combine for Final Answer: Combine the result and the sign to get the final answer. The final answer is positive 6. -3 + 9 = 6.

Answer:

Identify Signs: Identify the signs of the two numbers to determine if they are negative or positive. $\newline$ We have $-3$ (negative) and $+9$ (positive). $\newline$ Since they have different signs, we will subtract the smaller absolute value from the larger one.
Determine Absolute Values: Determine the absolute values of the numbers. $\newline$ The absolute value of $-3$ is $3$ , and the absolute value of $9$ is $9$ . $\newline$ Now, subtract the smaller absolute value from the larger one: $9 - 3$ .
Perform Subtraction: Perform the subtraction. $\newline$ Calculate: $9 - 3 = 6$ .
Determine Sign: Determine the sign of the final answer. $\newline$ Since the larger absolute value was from the positive number $+9$ , the result will be positive.
Combine for Final Answer: Combine the result and the sign to get the final answer. $\newline$ The final answer is positive $6$ . $\newline$ $-3 + 9 = 6$ .
