- (–125) + (–30) = –155 (Moving 30 steps left from –125).
- (+105) – (–55) = +160 (Subtracting –55 is adding +55).
- (+80) – (–150) = +230 (Adding +150 to +80).
- (–99) – (–200) = +101 (Moving 200 steps right from –99).

class 6 Mathematics Textbook Chapter 10 question answer
Evaluating these expressions using an unmarked number line:
• (–125) + (–30) = –155 (Moving 30 steps left from –125).
• (+105) – (–55) = +160 (Subtracting –55 becomes adding +55).
• (+80) – (–150) = +230 (Adding +150 to +80).
• (–99) – (–200) = +101 (Subtracting –200 becomes adding +200).
The unmarked number line helps visualize these movements, simplifying integer operations using directional movement.
