@Vocaloid help please

dude:

Add and subtract 20 from -3

dude:

2 possible locations

theghost22:

I'm confused

Vocaloid:

like dude said there are two scenarios: one scenario where S is on the left and another scenario where T is on the left:

Vocaloid:

|dw:1536695907031:dw|

theghost22:

So it would be 17 and 23?

Vocaloid:

in both cases, S is -3

Vocaloid:

|dw:1536695929467:dw|

Vocaloid:

since the segment ST is said to be 20 units long each time, in the first case you would add -3 + 20 to get T and in the second case you would subtract -3 - 20 to get T

theghost22:

ok so 17 and 23

Vocaloid:

hm, careful w/ signs, -3-20 is -23 so -23 and 17

theghost22:

ok
