in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5

happy to

the answer is 15 to your question

10 times 13 = 130

10 times 13 = 130

130 + 130 = 260

if this you out can you make this answer the brainliest?
