Question

Simplify by adding the numbers, –1 + (–6) using the number line.

• A. -7
• B. 6
• C. 5
• D. -5

Answer 1

The correct option is A -7

we are adding two negative numbers.
To start, locate the first number which is −1. Then, add negative 6 to it which means moving the existing point 6 units to the left of the number line.
Therefore, we have –1 + (–6) = –7.
