At this moment, Shard wanted to refuse, but Dorothy tugged at him. So he kept his mouth shut, thought carefully, and asked the safest question:
"Your Highness, how's your mathematics?"
"Very good, I have an excellent math teacher."
The Princess said confidently.
"The following problem involves addition and subtraction within thirty. Just give the answer within half a minute."
Shard said, and Princess Margaret's voice rose slightly:
"Within thirty? If it's not complicated continuous calculations, ten seconds or even five seconds will do."
"Your Highness's math is indeed excellent."
Sir Plisha also chimed in.
"Alright, please listen carefully, everyone can calculate together."
Shard coughed, and people looked at him, so Shard said:
"In the Northern District Hymn Square of Tobesk City, there is a Three Cats Inn. Three days ago, three gentlemen went to stay, each paying 10 pennies, a total of 30 pennies."
"Is it that cheap?"
Princess Margaret asked curiously.
