Which of the following is a correct interpretation of the expression 3- (-4)=
Choices:
A. Start at 3 on number line and move 4 to the left
B. Start at 3 on the number line and move 4 to the right
C .Start at -4 to the number line and move 3 to the left
D. Start at -4 on the number line and move 3 to the right
To evaluate $3 - (-4)$, we can think of it as "start at $3$ and subtract $-4$". When we subtract a negative number, it is the same as adding the positive version of that number. So, $-(-4)$ is the same as $+4$. Therefore, $3 - (-4)$ is equivalent to $3 + 4$. This means we start at $3$ and move $4$ to the right on the number line.
Therefore, the correct interpretation is $\boxed{\textbf{(D)}}$.
The correct interpretation of the expression 3 - (-4) is:
C. Start at -4 on the number line and move 3 to the left
