Question

Which addition does the model below represent?

Answer 1

Answer:

[C] 3 + ( - 4).

Explanation:

• First the arrow begins at 0 and moves to the right 3 spaces positive, ending at 3.
• Then it moves backwards, which is subtracting left 4 spaces towards -1 past zero.
• When adding a negative to a positive, you convert it to subtraction.
• 3 + -4 is the same as 3 - 4.

Correct choice - [C] 3 + (- 4).
