Question

I NEED HELP IN 5 Or Less MINUTES WILL FAN AND MEDAL PLEASE!



how would you use the additive inverse to find 4 - -5

Answer 1

remember

a - (-b) = a + b

Answer 2

i dont get it sorry im not that good at math lately

Answer 3

so let's say you're trying to find the distance between a and b
The distance would be
a - b


because a will be greater than b since it is to the right of b on the number line

but what if this b was a negative number?
so let's say b is something like -5 and a is 5

we need to find the distance between the two points

5 - (-5) = ??

We can look at a number line again


The distance from -5 to 5 would be the same as adding the distance from -5 to 0 and 0 to 5
-5 to 0 is 5
0 to 5 is 5
5 + 5 = 10

Now let's look at 5 - (-5) again

remember I said that a - (-b) = a + b

so 5 - (-5) would be the same as 5 + 5 = 10

So do you understand it now? :)
