Q. Which of the following is a correct interpretation of the expression

3-(-4) ?

\newline

Choose

1

answer:

\newline

(A) Start at

3

on the number line and move

4

to the left.

\newline

(B) Start at

3

on the number line and move

4

to the right.

\newline

(C) Start at

-4

on the number line and move

3

to the left.

\newline

(D) Start at

-4

on the number line and move

3

to the right.

Understand the expression: Understand the expression. $\newline$ The expression $3-(-4)$ involves subtracting a negative number from a positive number. $\newline$ Subtracting a negative is the same as adding the opposite positive number. $\newline$ So, $3-(-4)$ is equivalent to $3 + 4$ .
Perform the calculation: Perform the calculation. $\newline$ Adding the two numbers together, we get $3 + 4 = 7$ .
Interpret the result: Interpret the result on the number line. $\newline$ Starting at $3$ on the number line and adding $4$ means moving $4$ units to the right. $\newline$ This is because when we add a positive number, we move to the right on the number line.
Choose the correct answer: Choose the correct answer. $\newline$ Based on the interpretation, the correct answer is: $\newline$ B) Start at $3$ on the number line and move $4$ to the right.
