c) 3 + 5 = 0
d) Einhen ના

Answer 1

To add -2 + (-3), start at -2 on the number line and move 3 units left, resulting in -5. The addition of two negative numbers results in a negative number.

Step-by-step explanation:

The question asks to write the addition modeled on the number line for -2 + (-3). When adding two negative numbers, the result will have a negative sign. In this case, you are combining the negative values, which means you are moving further left on the number line from -2. So,

• Starting at -2 on the number line, move 3 units to the left to add -3.
• This lands you at -5 on the number line.

Therefore, the addition of -2 and -3 is -5.

According to the options given in the question, the correct answer is: -2 + (-3) = -5.
