Describe the location of the sum, relative to p, on a number line

P + (-2)

The location of the sum is 2 units before P (left to P)

Step-by-step explanation:

* Lets describe the number line

- A number line is a horizontal straight line with numbers placed at

an equal units

- A number line can be extended infinitely to the left and to the right

- A number line represents both positive and negative integers

- The numbers come on it from left to right

- The negative numbers come on the left of zero and the positive

numbers come on the right of zero

- Ex: - 5, - 4, - 3, - 2, - 1, 0, 1, 2, 3, 4, 5 part of the numbers on the

number line

- To add numbers on the number line we start from first number of

the addition and if this number is added by a positive number we

go to right, if the number is added by a negative number

we go to left

- Ex: 5 + 3 ⇒ go from 5 to the right 3 units, then your position is at 8

2 + (-3) ⇒ go from 2 to the left 3 units then your position is at - 1

* Now lets solve the problem

- The sum of P + (-2)

∵ Your location is P

∵ You will add P by (-2)

- Negative number means you go to the left

∴ Your position will be before P by two units

∴ The location of the sum is 2 units before P (left to P)
