How can the additive inverse be used to evaluate the problem below? –3 – (–6)

Answer is 3

Step-by-step explanation:

For the set of all real numbers we find that additive identity is 0 such that

for all x in R

and inverse of x is -x for all x in R

Using this here we want to subtract -6 from -3

Instead of subtracting -3 we can add 3 the additive inverse of -3

Hence

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
