Identify Signs: Identify the signs of the two numbers to determine if they are negative or positive. We have 3 which is positive, and -7 which is negative. Since they have different signs, we will subtract their absolute values.Focus on Absolute Values: Focus on the absolute values of the numbers, which are 3 and 7. Should we add 3 and 7 or subtract 3 and 7? Since the signs are different, we subtract the smaller absolute value from the larger one. Subtract: 7 - 3Perform Subtraction: Perform the subtraction of the absolute values. Calculate: 7 - 3 7 - 3 = 4Determine Final Sign: Determine the sign of the final answer. The absolute value of 3 is 3, and the absolute value of -7 is 7. Since -7 has a larger absolute value and it is negative, the final answer will be negative.Combine Result: Combine the result from Step 3 with the sign determined in Step 4. We found: ● 7 - 3 = 4 ● The final answer for 3 + (-7) will be negative. 3 + (-7) = -4

3+(-7)=

Identify Signs: Identify the signs of the two numbers to determine if they are negative or positive. $\newline$ We have $3$ which is positive, and $-7$ which is negative. $\newline$ Since they have different signs, we will subtract their absolute values.
Focus on Absolute Values: Focus on the absolute values of the numbers, which are $3$ and $7$ . Should we add $3$ and $7$ or subtract $3$ and $7$ ? Since the signs are different, we subtract the smaller absolute value from the larger one. Subtract: $7 - 3$
Perform Subtraction: Perform the subtraction of the absolute values. $\newline$ Calculate: $7 - 3$ $\newline$ $7 - 3 = 4$
Determine Final Sign: Determine the sign of the final answer. $\newline$ The absolute value of $3$ is $3$ , and the absolute value of $-7$ is $7$ . $\newline$ Since $-7$ has a larger absolute value and it is negative, the final answer will be negative.
Combine Result: Combine the result from Step $3$ with the sign determined in Step $4$ . $\newline$ We found: $\newline$ ● $7 - 3 = 4$ $\newline$ ● The final answer for $3 + (-7)$ will be negative. $\newline$ $3 + (-7) = -4$
