3+ (-6)
(a) Draw two arrows to show 3+ (-6).

Answer 1

To add 3 and -6 using a number line, start at 3 and move 6 units to the left to get -3, or start at -6 and move 3 units to the right to get -3.

Step-by-step explanation:

Adding on a Number Line

To represent 3+ (-6) on a number line, start at the number 3 and move 6 units to the left (because -6 is negative). This gives you an arrow that points to -3. So, 3+ (-6) equals -3.

Alternatively, you can start at -6 and move 3 units to the right (because +3 is positive). This also gives you an arrow that points to -3. Therefore, 3+ (-6) also equals -3.
